So this month I've had college finals and was very stressed. There was also a time where I was so stressed and freaked out that I was pregnant (pretty sure I am not) but my period started on the 27th and it has been very light compared to my normal period. I had a bad cramp when I first started but haven't had any since. I normally have to take medicine every 5 hours for my cramps. My boyfriend and I "went through the motions" of sex but he had tight underwear on and a pair of shorts. I also had underwear on. My periods are always the same until this one. I've heard stress can cause light periods and I've also heard that pregnancy can cause them. Hopefully someone can tell me if they believe it is stress or something different. Thanks in advance!
