Help please!!

I have very nervous to post anything; or really even talk about it. I wanted to know everyone’s thoughts on my being unsure about whose baby I could be pregnant with. Here are the dates and details. August 21/22 I had unprotected sex with guy #1 he did cum inside of me... September 21 I did start my period and it was lighter then normal but still lasted a full 3-4 days. September 22 & 23 I had unprotected sex with guy #2 who came inside of me and again October 2nd and 3rd with guy #2.

As of right now I am exactly 25 weeks and 5 days pregnant. I first went to the doctor when I missed my period in October. My first ultrasound was October 31st and the baby was said to be 5 weeks and 5 days. I know they are playing in the first day of my last period. I have talked to my doctor about this. I don’t know if I’m being paranoid or if I just need reassurance. I would really appreciate kind helpful thoughts and opinions.
