Okay, so I'm 15. Today is the 12th of August and I lost my virginity on the 3rd (we DID use a condom). And then on the 7th I had sex again, this time he did NOT use a condom, and I'm not on the pill. I didn't mark down when my last period was, but I'm sure it was about 2 weeks before I lost my virginity. And today I noticed I was bleeding a tiny bit.. That's only about 3 weeks since my last period?.. My breast have been sore, and I've been feeling nauseated sometimes (some pregnancy symptoms i read about). anyway I'm really worried i might be pregnant because I also read online that some woman get their period really early in their pregnancy. I apologize if this is all kind of hard to understand but I'm worried and would appreciate a nature answer. Thanks.
