Hi I was just diagnosed yesterday with something called Adenmyosis it is a thickening of the Uterus and it caused me to think I was pregnant I never missed a period but it does cause missed cycle,Heavy periods Clotting If you want to know more go to Mayo Clinic Website and search it. I had to go to 4 different doctors before they finally figured it out by doing a Pelvic Ultrasound Good Luck!!! God Bless
Im using nuvaring. That past 4 months I have had spotting only. Im definatly not pregnant as Ive have 2 negative tests and I would be showing my now. The doctor said, stress, (even if you dont feel stressed) or diet and exercise change could be to blame.
