About 2 1/2 months ago, I knowticed a tiny bit of dry brown creamy stuff on my underware, I changed my underware and the next day there was a tiny bit more, then around 10 am there was a coupple dots of red. It turned to brown again after that. For the next two days the brown stuff was there, but only the tinyest bit, but only between 9am and about 3pm. What was that?
