So I have been having unprotected sex with my boyfriend for just under a year after coming off of the pill. On September 10th we broke up however we did have sex a few times after this in the following days. On September 24th I had protected sex with a condom with another man. On 14th October I found out from an ultrasound that I was 5 weeks and 5 days pregnant. My dates have matched up exactly to this day ever since. I have been given a due date of 11th June. What do you think from the dates of conception? And who do you think the father will be? I know protection should rule it out but I am paranoid that I fell pregnant so close to having sex with a different person after not falling pregnant with my boyfriend.
