Someone please help me 😭i’m under age with anxiety and I’m freaking out !!!!!!😥😥

I’ve had sex (always protected) only about 4 - 5 times now and he hasn’t cummed every time we've had sex. The three times that he has cummed we’ve always always used a condom and he’s always pulled out of my vagina before he starts ejaculating. We also check the condoms for holes by filling them with water afterwards and there’s never been any holes. The first time I had sex I took a morning after pill because I get really bad anxiety from the fear of getting pregnant as I am under age (yes yes I know I’m a very very stupid girl).

I haven’t had a normal period since the 9th of December which was before I took a morning after pill. The only other 'period' I’ve had since then was a short two day light period from the morning after pill side effects . It’s been a few weeks after and my periods due in 12 days and I just finished my fertile window two days ago. Had protected sex yesterday and used the same method of pulling out with condom and filling it up with water afterwards but I got bad cramps yesterday afternoon after it all and have had sore breasts but that could just be because of my cycle. I’m not on birth control.

I HONESTLY DON’T KNOW WHAT THE HELL IS HAPPENING. Do you reckon I could be pregnant? I have really bad anxiety and this stuff just eats me alive.
