I'm nearly 21, not sexually active, I was on birth control for a while but I haven't taken it in six months or so. It's been a month and a half since my last period which was very light compared to what I normally get.
Saturday on a trip with my college I started getting really bad cramping pains every half hour or so lasting for 10-5 minutes and they'd stop. After walking(a mile or so) for a while the cramps calmed down and only because mildly uncomfortable. Yesterday the cramps started up again, leaving me in bed for the better part of the afternoon, and died down later on.
This morning when I went to the bathroom I noticed menstrual blood an the bath tissue and put on a pad and forgot about it. Later in the afternoon the cramps came back worse then the past two days, so I went to the bathroom and noticed there was no blood what so ever on the pad. The camping is getting a bit better now(about 4 hours later), but it's still really annoying. I talked with my mom and she said to watch it and see what happens, but I'm worried that there might be something more to it. Any advice?
