Please help

Jacinta

I’m 16 days late for my last period. I’m 15 years old and i have sex with my boyfriend like once a week when I see him or a couple of times in that one day. 2 months ago my whole cycle changed on a totally different date, the next time I got my period which was the last time it was very light. Lightest I ever got. We have gone raw a couple of time but we always pulled out every 30 seconds to just make sure. I would suck his dick and he would wipe the pre cum away if there was any and he also pulled out when he was about to cum. Other times we use condoms. ALL THE TIME. This was a one off that we didn’t protect ourself while having sex. And this was only a couple of weeks ago when I was actually due for my period. So it wasn’t like when my fertility window was active. My periods wernt very regular. Some days I could be late and some days I was early and sometimes I missed my period. I’m not stressing stressing at all. I don’t have any signs of pregnancy but I am just curious. I always get told that our bodies are just really weird and yeh. Please help me out!! Thank you xxx
