So please dont judge but i know im pretty young. I recently turned 15 not too long and i had loat my virginity at a fairly young age, so the who sex topic is nothing new to me. I have always had sex with long my then long term boyfriend. It had been 2 years but we recently broke up about a month ago. And i was pretty upset but i went looking for a rebound. I had a pretty close guy friend so i hooked up with him and we ended up having sex. This was on the 23rd of this month. Well basically after a bj her came on his stomach and i had no idea but we had sex after and it was fine. I later asked him if  he came and he said yes but before we had sex. This scared me because in all honesty i didnt realize we had unprotected sex (it was in the moment and i didnt really pay much attention. Please dont call me immature for this bc im quite mature for my age it was just an honest mistake) and basically i was terrified bc i know that even if a male doesnt ejaculate inside of me, there is still a possibilty of sperm to enter the vagina. I was way past my fertile window and i was supposed to have my period four days later, on the 27th but i never got it. I read into it and it says there is a very low chance of pregnancy after ovulation but there still is a chance. I know im too young to be pregnant or even take care of a child and i was raised in an abstinence family (i rebelled a lot due to this) but please help. Im not sure if im over thinking this or not but im 4 days late on my period and im almost always on point with my period. Its now too late to take a plan b pill and i have no way to get a pregnancy test or a ride to planned parenthood, im just terrified and my family will disown me. They've said it before and im just scared. Someone please help me
