Hi. It's been about 2-3 weeks since my period. I started about a week after it finished to have brown discharge. It's sometimes got little brown bits of what looks like old blood. It's still happening. It doesn't smell. It's sometimes. Goes up and down in amount. Sometimes get a little pinch of pain in my abdomen but doesn't really hurt it's just an odd feeling. I'm not sure what to do. I have sex fairly often including during my period.
