I have always had premenstrual spotting and was diagnosed eventually with endometriosis. Sometimes, endo causes infertility (as it did in my case) but many endo sufferers do conceive and give birth to babies without trouble.

It may not be endo but it is worth bearing in mind that spotting is a key symptom of endo. I notice you mentioned having pain bad enough to use Naprogesic ... that would also make me suspicious.

The only way to have endo diagnosed definitively is by laparoscopy. If it is found during that procedure, it can be removed.

As I said, if that's what you have, you may not have trouble conceiving but if you do, it is worth consulting a gynaecologist to have it checked out.

Kind regards,

Mel

Edited to add: I forgot to say that endometriosis is a condition where the lining of the uterus is present in other places in the body, usually around the reproductive organs and bowel. During menstruation, the lining bleeds, causing pain and possibly leading to adhesions in the abdominal area.
