That is going to be too close to tell. You are going to need a paternity test after the baby is born.

Definitely need a DNA test

Unless you were actively testing for ovulation, you will never know what day you ovulated on. Those online calculators give estimates based on when most women might ovulate.

Add to that the fact that some sperm can live for days and you could have ovulated earlier. So, really, you won't know the paternity of the child until a DNA test is done.

If you have had sex with 2 people within the same month, it is always recommended to get a paternity test.

Good luck with your pregnancy.

Saw midwife today and she said based on the sono and HCG levels We more than likely can narrow it down, if not there is something called a prenatal DNA test done wither by amnio or Chorionic villus sampling, can be done between 8-12 weeks, im just so scared it was stupid what I did while me and my boyfriend were broke up Definitely a lesson learned, but i pray it's not my Xs baby because he is not someone I would want to be a father!! But Given that I was on birth control I think that I ovulated later which my midwife confirmed
