Abortion advice

So i had a abortion in July 2015 that really messed me up, it made me very paranoid about my body and the thought of not being able to conceive again. I would go to the doctors all the time for the slightest problems and request pelvic scans at-least every 3-4 months always thinking something was wrong with me since the abortion.

I got with my ex around December 2015 and we always had unprotected sex and tried for a baby for about 8 months and i never got pregnant once which made me even more paranoid. I promised myself i would never put my body through an abortion again if i did manage to conceive.

We broke up early February this year because he cheated on me😒

.........Long story short i met someone new in may and we had been seein eachother for a while we had unprotected sex once because we were drunk..and i never thought i would say this but i am scared i am pregnant, for the last two weeks he has done some things that has put me off him completely and i can't see any possible way of having a child with him and being happy about it im scared of being pregnant because i will probably end up getting another abortion which i promised i would never go through again. Am i being selfish to myself for doing this?????

Its just that i cant see myself having a child and being stuck with someone i have no connection with at all. I wanna have kids with someone i love but im scared the abortion will start making me paronoid again!?
