What else should I check?

This is the 11th cycle we're trying, AF due the 20th, but I already started to  cramp. I don't even bother anymore to think or hope that it's just my uterus adjusting to a new baby. I KNOW AF is around the corner. My husband got his sperm tested and it's everything great. I had cysts that made my periods irregular as a teen, but after 13 years on the pill, I've had none and after almost 2 years out of the pill I still have regular periods and no cysts. I'm only 30. I've never had clamydia, but still got tested and it was negative. Had some ultrasounds and it looked fine. I'm going to do a HSG in January, so we'll know more by then. I can't stop feeling sad for not being pregnant yet. I know there are many out that are on this journey much longer, but I just can't stop feeling sad about it. What else could be going wrong?
