so my period has lasted way longer than it was supposed to, lasting 3 days usually but it's been six days, but very little blood. Like nearly non-existent. I've been getting really short pains in my lower abdomin but not cramps. When I described them to my friends, they said it sounds like I'm having contractions. They're getting closer together and stronger. It's really worrying me and I dont know what's wrong or what to do. can anyone give advice or help? side note, the pains started yesterday.
