I was recently put on birth control about 3 months ago. I have taken the pill religiously everday in the morning. I normally get my period on the 12. But it came early today on the 7th. I put a tampon in as normal and I went to wipe and there was a piece of gray tissue about half the size of my pinkie in length. My boyfriend and I are sexually active and we use a condom and I'm on birth control. Was the grey tissue a sign of a miss carriage? I haven't had any pregnancy symptoms either.. Help me I'm scared
