Filly ~ I used to get something like that too. But I dont know what for sure could be causing this in your situation. Could be a number of things. Your best bet is to go see a doctor about it and get things checked out. I will leave you a link of what happened with me. I ended up having this for years and years. Till finally almost 8 yrs ago I had a supracervical hysterectomy. I hope this isnt what is going on for you . I also tried a D&C before the hysterectomy and it didnt solve the problem for me. http://women.webmd.com/tc/dysfunctio...topic-overview

Please go get it checked out and go from there. It could be stress , hormonal , meds any number of thinks. Its just best to let someone trained to check things out like a Gynecologist. Take care ok? Thinking of you!!
