Hello Dr. I am 30 year old single lady. I have normal periods. Cramp and 7 days flow. Last month my period date was 26th August. But since yesterday I see blood coming mixed with white discharge. It's not like period flow. But since last evening, 4 times I have seen blood. It 's a bit dark red in color. And thick. And yes, I have also started workout session since last 3 days. Before six month or long, Same thing happened. That time also I had started working out. Please tell me what it can be? And what's the solution?
