I'm 17 years old, and I'm not sexually active. I should be getting my period right now, but instead I'm just getting a light flow of really dark and kind of thick blood, and I have been for the past 5-ish days. A couple days before that it was so light I thought I was just spotting, and I was very confused. Last month, right after my last period, I had some spotting about 7 days after my period, which scared me terribly, and since then I've been all stressed out over it. I was also started on some antibiotics for a skin infection, but I just finished those today. I've been dealing with some emotional stress from school, and I've been getting more exercise in gym class than I normally would at home. I also started horseback riding during the summer after 3 years off of it.
I have some weird anxieties about getting pregnant. Nobody else's genitals have never touched mine, and yet I worry about this constantly. I'm not on birth control. If anybody could just make me feel a bit better about this, that would be lovely. Thanks a bunch (:
