My cycle usually starts around the 20th or so of each month and about the second and third day of it I get this extreme aching feeling in my vagina. Umm its hard to explain since I don't know any technical terms but anyway it just is a throbbing pain that only subsides if I put pressure on it like sitting down. It doesn't last the whole time of my period, usually just about the second and third days of it.
Also recently I have been getting cramps about a week before I'm supposed to start and have been spotting brown about a few days before I start.
Please help! Is this normal ladies? Anything I can do to prevent it? What could be causing it?
