Warning:Really dumb and ridiculous sex Q

So dumb that I’m posting anon lol. Because I know I’m gonna get some 😆🤔 and “should you really be having some sex” comments.

ONWARD. I just had my son 3 months ago and all birth control wrecks my body but I decided in feb(?) I would try Liletta IUD per my GYN recommendations. 3 painful and failed insertions later, he said we’d have to wait because my Cervix was not cooperating. I was 6 weeks at the time. So before my son we’d used Nexplanon until I realized it made me gain 50 lbs and gave me ovarian cysts. - Why am I dragging this on?

We’d used pull out method hundreds of times with obvious great success and now I am starting to worry because my periods have been on time ( they never are ) and I am due to start. But I had some moderate cramping a few days ago,and before my son I had never cramped. That’s how I actually knew/found out I was pregnant at 3 weeks along.

The question is, if he came on my back/bottom and it dripped what are the chances I could even get pregnant?! I read very low but am I really that unlucky?😩

I took a test and it was Neg. I plan to retest next week if I don’t get my period.
