Can I have some advice. Please no hate.

hello.. I know I’m new here but I came here for some reassurance.

my baby father/boyfriend (he is the same person..) just asked me for a dna test out of now where and that makes me extremely nervous...

because I made poor decisions, on the 14th of March I slept with a African American man using a condom. He did not finish, and my doctor told me condoms don’t get small rips, they tear and bust open. We stoped having sex because I felt uncomfortable. I was told sperm can live in you for 5 days. On March 21 and 22 I noticed a lot of clear stretchy discharge after having unprotected sex with my current boyfriend and he came in me 2 or 3 times. About two weeks later April 5th I got a faint line on a pregnancy test. I told him it was his baby and he accepted it, all of a sudden out of no where he asked me to get a dna test, I agreed. I’m so concerned I’m going to loose my boyfriend. I talked to my doctor she said I’m over reacting because of my anxiety and that the conception dates and my 20 week scan match up perfectly I was like 19 w and 4 or 5 days something around there. They thought I was farther along and pushed the due date back. The doctor said count 38 weeks back from your due date and that is your conception date. I did that, and got March 22. I love my boyfriend I’m so worried I’m going to loose him from being a whore. It’s really how I feel. Do you think I should worry ladies ? 😔

Also I didn’t cheat he asked me to be his gf March 31st we where hooking up casually before that.
