Does having lots of sex change your period or anything? I've had pretty regular, light and short periods all my life, until about June, when I got with someone and we had a lot of sex, and my next period (July) after getting with him was horrible, lasted almost 3 times as long, and had me about on the floor with cramps. Then August was shorter, September was hell again, and now I'm late. But, I haven't been with anyone since like, the beginning of August. Just confused and wondering if like daily sex has any impact on periods

Also, I'm not on BC, and have never been on it.
