I have been having very light periods for the past couple of months, but this month it was verrrry heavy. The other day, when I was changing my tampon, a giant slimy bloody mucusy thing came out of my vagina. I was sooo scared, I dont know what it was! It was thick and about 4-5 inches long. Was it my lining? Was it a fetus or something? I just dont know what it could have possibly been and Im really freaked out. Please reply! :'(
