I was on the pill for 3 months. I used it because i had endometriosis. I took my last pill the 28th of May. I must begin my period on the 24th. But for about a week or so i have discomfort in my abdomen. Feels like its heavy and at times I get some cramps and it feels the hole time like i''''m gonna start my period at any time. I urinate very often and I have to go more often for no2. What can it be? It feels like maybe my ovaries. Please Help!! Thank You
