Period

Okay so on may first I had lost my virginity I’m 18 btw. And me and my boyfriend had sex like 4 times that month one time unprotected yes I know I shouldn’t have but at the time it I wasn’t thinking but we did it for a couple of strokes he didn’t ejaculate even the other times he didn’t my first period wasn’t late it seemed different to me but it was heavy for like 2 days and this month my period was heavy and normal actually really heavy not crime scene heavy but blood clots heavy but I’ve been thinking because some people said that they had their period while pregnant including my mom with me and that just scares me because I’m absolutely not ready to bring a child into this world right now. And not to mention I took a pregnancy test last month and it was negative)
