My period has become irregular. I'm not pregnant. Because I took a pregnancy test and it said negative. But it hasn't been coming out and on the 18th it came but it was little blood. I would wipe and see period blood but it never seep through my clothes... like I could walk around in my underware and not haft to worry about blood seeping through. Now ever since I was little I would skip three months. And its still like that. Its been like this since may or June.can you help.. I think something serious might be wrong with my body
