ok so i am 19 years old and have had my period for 7 years now. even when i first started the first time ive never had any problems with it not even irregular periods. but this time it has been very different. my fiance and i are now sexually active and im wondering if whats going on has anything to do with it. i started my period on the 29th of january and now its the 8th of february and it still hasnt gone away. it stopped for about an hour on the 6th day started back, ended again on the 8th day, started back again and happened like that again today. it doesnt look the same as it normally does. usually its a bright red but now its like brown with like white mucous looking stuff mixed in with it. can anyone tell me if this is normal or not?
