Question
I had my period from December 13th to 17th in 2018, and my ovulation day was on the 30th. On the 31st, I had sex with my husband, and I also had sex with my husband before the 30th. On the third day of the last day of my ovulation period, I accidentally got drunk and had a one-time sexual encounter with someone else. Whose child could it be? My period is four days late.
Answer
In this situation, aside from confirming that the child is yours, no other conclusions can be drawn. If you confirm the pregnancy and decide to carry the child to term, and are sure you love this child and have the ability to raise them healthily, then you can focus on your pregnancy. At 9 weeks of pregnancy, you can take a fetal villus sample, or after 16 weeks of pregnancy, you can perform amniocentesis to extract fetal cells for testing to confirm the biological father of the child.
