I’ve been having cramps for four days or so but have had no sign of any bleeding. Usually DTD will help to bring on the bleeding, but even That isn’t working. We’ve been TTC for three months. I usually never miss a period and am prone to having very heavy and painful periods due to having endometriosis and adenomyosis. However my last period only lasted two days and there wasn’t much blood at all. I tested last month as I figured that light period could have been implantation bleeding but got a BFN. Has anyone experienced anything like this before?
