Ovulation usually occurs around day 12–16 of the cycle
Sperm can survive up to 5 days inside the body
The egg survives about 24 hours after ovulation Pregnancy happens only if sperm is present during ovulation
The partner from November 27 has a MUCH higher chance of being the father The November 17 encounter is extremely unlikely to be responsible
Important note
Only a DNA (paternity) test can give 100% certainty Non-invasive prenatal paternity testing can be done from 10 weeks of pregnancy using a blood sample from you and a cheek swab from the alleged father
Hello dear See it is a medico legal issue. There may be requirement of amniocentesis which is to be recommended by gynaecologist only. I suggest you to please get in person consultation with gynaecologist in person for better clarity Regards
Hello Carter In this case, since you had sex on November 17th, one day after your period, and then again on the 27th, the timing suggests that the person you had sex with on the 27th may have a higher chance of being the father. This is because sperm can survive in the female reproductive tract for several days, but ovulation typically occurs around the middle of your cycle.
Thank you
To determine who is more likely to be the father based on timing, consider the ovulation cycle. A typical menstrual cycle lasts about 28 days, with ovulation occurring around day 14. You mentioned having sex on November 17, one day after your period, and on November 27. If your cycle is regular, ovulation would likely occur around 14 days after the start of your last period. Having sex one day after your period, around November 17, is less likely to coincide with ovulation, assuming your cycle is approximately 28 days and regular. Sperm, however, can survive in the female reproductive tract for around 5 days, which does leave a slight chance for fertilization if ovulation occurred earlier than expected. The encounter on November 27, closer to a typical ovulation window if your cycle is average, could have higher chances of conception since it aligns more with a typical fertile window. Still, understanding individual cycle lengths and variations is crucial. Since questions like these are sensitive to individual variances and significant in consequences, a paternity test would be the most accurate way to confirm the father’s identity. Discussing this with a healthcare provider could aid in exploring these options and obtaining reliable DNA testing once the baby is born. Always consider discussing your concerns with a healthcare professional to gain clearer insights and guidance.
Hello Carter, thank you for sharing tour concern. Based on your explanation the partner on 27th Nov has more chance, but we can’t be 100% sure without a paternity test.
Kindly visit a certified Gynecologist or a Family Physician for further evaluation and management.
