2 weeks ago I had my period.. it was very light like spotting for a couple days.. & it was all brown blood no red.. idk why or whatit could be.. I've since had cramping feels like menstrual cramps but there not.. now my breast mainly my nipples have been extremely sore & sensitive even to the touch.. Please if anyone could help me & give me any feed back please do thank you..

My first question would be have you taken a pregnancy test? If you have and it's negative then I wouldn't be too worried. I've had these issues, also. I would go on about factors that change your period and mess with your hormones but I'm not a doctor and it doesn't change the fact that you might want to bring this up to a doctor if it persists.
