Listen , should I just live my life ?

This happened all the way back in July me a a partner were fooling around but I’m still a virgin and he didn’t put it on my private and he never came he just like rubbed it on my bum and I guess thought he was trying to do anal but e never entered I will not allow that , stress has made my period irregular I took 2 tests one 5 weeks after it happened and one 13 weeks after it happened they were negative I have gotten all of my period after that the first one was 5 days and then the ones after that varied to like 3-4 days but they have always been very heavy with clots . I also went to the doctor for my weekly checkup a couple weeks ago I think I would have been 15-16 weeks by then but he felt my stomach felt no lumps and checked my pulse and heartbeat everywhere and said everything was fine .....
