Hi, I m on birth control and have been for the last several years due to the fact that I had horribly painful periods and for a while had to deal with cysts on my ovaries. Yesterday and today I had a bout of heavy spotting between periods, almost as if I was on my normal flow. Earlier this evening I had bad cramping with the spotting and when I went to the bathroom after, I realized what looked like a massive clot on my pad. Being the oddly curious person I am, I checked it out and it squishy and not very bloody. I was curious to know if you had any ideas as to what may have been the cause of this odd thing.
