I should have taken a picture but today I am on my period and just started birth control again. I started the Nikki birth control. Today when I wiped there was a pea like size thing of blood and I thought it was a clot. But when I went to press it between the toilet paper I noticed that it was hard. I can’t find anything on the internet explaining this. I am in the process of getting tested for pcos. I am overweight. If anyone has any experience with this please comment. I am at a loss at what it could be. I did not think clots in period were suppose to be hard.
