Thanks for sharing the full timeline – it helps a lot.
You had unprotected sex, then a negative pregnancy test (blood + urine), but now pain + irregular bleeding + soft smelly stool. Here’s what could be going on:
🔎 Possible causes (even with negative pregnancy test)
1. Early ectopic pregnancy – Rare but serious. Blood test can be falsely negative very early. Pain + spotting + negative test does not rule it out. 2. Pelvic Inflammatory Disease (PID) – Infection after unprotected sex. Causes lower abdominal pain, irregular bleeding, sometimes loose stools from pelvic irritation. 3. Ovulation bleeding + cyst – Mid-cycle spotting (around day 14–16) with a painful ovarian cyst can mimic this. 4. Hormonal imbalance – Your cycles are short (18 days between periods). This can cause breakthrough bleeding and cramping. 5. Bowel infection (gastroenteritis) – Explains soft smelly poop, but not the bleeding. Possibly two separate issues.
⚠️ Why the negative test doesn’t fully reassure
· Ectopic pregnancy can show negative urine and even low positive blood test – but levels may be too low initially. · PID doesn’t affect pregnancy test at all.
✅ What you MUST do now
1. Repeat blood pregnancy test (quantitative hCG) – not just urine. 2. See a gynecologist today for: · Transvaginal ultrasound (looks for ectopic, cyst, or fluid in pelvis) · Pelvic exam + swabs for chlamydia/gonorrhea 3. Go to ER immediately if: · Pain becomes sharp or severe · Bleeding increases (soaking a pad/hour) · You feel dizzy, faint, or shoulder pain
📌 For the soft smelly poop – likely a separate mild stomach bug, but tell your doctor.
I’m a urologist – this is a gynecological issue. Don’t wait. Even with negative tests, your symptoms need a doctor’s exam today.

The symptoms you’re describing—lower abdominal pain, abnormal bleeding patterns, and changes in bowel habits—could be attributed to various factors. First, hormonal fluctuations or imbalances might cause irregular bleeding or changes in menstrual cycle. Stress, dietary changes, or sleep irregularities could also be factors affecting your cycle. Another possibility could be a mild gastrointestinal issue leading to the abdominal discomfort and altered bowel movements.
However, there’s also the possibility of a gynecological condition such as a uterine fibroid, ovarian cyst, or endometriosis which could explain the abdominal pain and unusual bleeding. Infections, such as pelvic inflammatory disease (PID) or urinary tract infection (UTI), can also cause similar symptoms, including abdominal pain and cases of abnormal discharge or bleeding. It’s encouraging that the pregnancy tests came back negative, but it would be prudent to consider a visit to a healthcare provider for a more thorough evaluation. They might recommend an ultrasound or additional blood tests to help identify the root cause.
In the meantime, keep track of your symptoms—note when the pain occurs, the nature of the bleeding, and any other changes in your cycle or bowel habits. Avoiding potential irritants such as caffeine or spicy foods may alleviate bowel symptoms, but consult a doctor if pain becomes severe or you experience heavy bleeding or fever. Given the complexities and variations in cycles and symptoms, professional assessment ensures accurate diagnosis and management, prioritizing your overall health and safety.
Hello dear See at your age this can be attributed to hormonal alterations or physiological variation Also there can be chances of PCOS. Iam suggesting some tests for confirmation of exact diagnosis. Please share the result with gynaecologist in person for better clarity and for safety please donot take any medication without consulting the concerned physician Serum ferritin Serum tsh Serum prolactin Serum progesterone Rft Lft CBC Urine analysis Pelvic USG Serum estrogen Serum progesterone Hopefully you recover soon Regards
Hello, thank you for sharing your concern. From your history, this does not strongly suggest pregnancy. Pregnancy is very unlikely, but we’ll still keep it in mind if symptoms worsen. Your issues might be due to Hormonal imbalance ir anovulatory bleeding or gut related pain, etc. Even though risk is low, we will have to rule out ectopic pregnancy if Pain becomes severe and continuous, Dizziness / fainting, Shoulder pain appears. In that case, repeat Urine Pregnancy Test, Blood Pregnant Test & Ultrasound of Abdomen+Pelvis. Here is my further advise-
1. Wait and observe for this cycle- This kind of irregular bleeding often settles on its own.
2. Repeat pregnancy test- Do it 2–3 weeks after intercourse if still unsure.
3. For pain- You can take Tab. Paracetamol 650mg when needed. Manage gut by Light diet & Avoiding gas-forming foods.
4. Track next cycle- If cycles remain irregular, evaluation needed.
Physically See a doctor if: Bleeding becomes heavy, Pain becomes severe, Irregular cycles continue for 2–3 months.
This is Most likely hormonal irregular bleeding + gut-related pain. Pregnancy is very unlikely given negative tests. Usually self-settling, but monitor symptoms.
Feel free to reach out again.

Hello Thanks for sharing all those details; it really helps to understand your situation better. Let’s break down what you’ve experienced:
1. Menstrual History: - Last period: March 1-4 - Next period: March 22-25 - Unprotected sex: April 6 - Negative pregnancy tests: April 12 (both strip and blood) - Period-like bleeding: Started on April 16, brown blood initially, then red, followed by brown spotting on the third and fourth days.
2. Symptoms: - Ongoing lower abdominal pain that starts and stops, along with soft, smelly stools. - Spotting continues today.
### What This Could Mean: - Irregular Periods: Your bleeding on April 16 could be a lighter period or breakthrough bleeding, especially since you had unprotected sex earlier in the month. The brown blood often indicates older blood, which is common at the beginning or end of a menstrual cycle. - Hormonal Changes: Stress, hormonal fluctuations, or changes in your body can lead to variations in your menstrual cycle, including lighter periods or spotting. - Gastrointestinal Symptoms: The abdominal pain and changes in bowel movements could be related to digestive issues, which can sometimes coincide with menstrual symptoms.
### Next Steps: 1. Monitor Your Symptoms: Keep track of your bleeding and any abdominal pain. If the pain worsens or if you have any other concerning symptoms (like fever, severe pain, or heavy bleeding), it’s important to see a doctor. 2. Consider Another Pregnancy Test: If your symptoms continue or if you have any doubts, you can take another pregnancy test a week after your expected period or consult a healthcare provider for further evaluation. 3. Consult a Doctor: If the abdominal pain persists or if you have any unusual discharge, it’s best to consult a Gynecologist to rule out any infections or other conditions.
Thank you
From your timeline, pregnancy is very unlikely since both urine and blood tests were negative, and the bleeding you had on the 16th (brown → red → spotting) fits more with a hormonal/irregular period or ovulation disturbance rather than implantation. The on-off lower abdominal pain with loose, smelly stools points more toward a gut issue (like mild infection or IBS) combined with cycle-related hormonal changes, not something serious like pregnancy. Still, because your cycle suddenly changed and pain is persisting, you should see a Gynecologist for an exam and possibly an ultrasound to rule out cysts or infection and help regulate your cycle.
