A while back [ last year] I missed my period for 3 months. Since then its kind of been on and off. Most recently, i had a period but it wasnt really as heavy as it normally was. After that around 20 days after i have been spotting pinky discharge and sometimes with a little more blood. Its now been like that for over a week. My chest feels sore like i am having my period. Is this normal? I am going to go to the doctors anyway, just looking for some reassurance.
