I've never had as much trouble as you have but I would sometimes go two or three months before I would start. My doctor also put me on the pill. All that did was make me hurt.Besides, It is difficult to get pregnant on the pill. I found another doctor. He immediately suspected endometriosis. Surgery confirmed it. Laser surgury to remove the scare tissue did wonders. I was pregnant within three weeks!!! And pregnant again three months after my first son was born!!!! That's right! My boys are eleven months and three weeks apart! Find another Doctor!!!! If he/she doesn't listen find another!!!!
