I started with my period on Thursday after months without because of the birth control pills. (Because of hard training I skipped it). It chose to have my pill free week since my boyfriend is on vacation. On my period, I had a lot of pain (still have), it was hard to walk, wasn't up for food, and was also very nausea.. Now I'm finished after four and a half day which is very normal, but it still hurts a lot! And specially on my right side. So, I read on the internet about appendicitis, since I have a lot of the syntomps. Also afraid I can be pregnant, but I had my period,and also use birth control pills. Can it also be that I just waited to long with the period. Maybe more than my body could handle? Since the period started the same day as I started the non pill week?
