I had sex with my ex boyfriend the 20th of January and had a "period" at the end of January. I started seeing a new guy and we had sex the 4th of February we used a comdom and he did not "go". I am now pregnant. I had spotting and cramping starting the 20th after intercorse and it continued so I went to the hospital the Feb 23 and they said my hgc was 83. Who is most likely to be the father.
