Do I need a paternity test?

[Tua28054]

Do I need a paternity test? I had sex with an ex on 6/23/13. We did not use protection but I did take the morning after pill the next day. A week later I got back with my current boyfriend. I got my period on 7/4/13 and again on 7/28/13, which is normal because I have a 25 day cycle. I missed my period for August. Ii took a home test which was positive. I had an ultrasound on 8/26/13 where no fetus or sac was seen thus they did a blood test which showed my hcg at 100.5. 8 weeks later I had another ultrasound which gave me an Edd of 5/3/14. Every ultrasound since has coincided with this due date. I only had sex once in June with my ex and have only been with my current boyfriend since then. Is there anyway my ex could be the father?

If you go to Google and type in reverse conception calculator and put in your due dates and info it will show you conceived the first week in august. If your worried you could ask your doctor
