I agree 100% with Kathy. If you have been trying to conceive for a year, then you absolutely qualify to be seen by an infertility specialist.
I had very horrible periods from my very first one at 11--I won't bore you with the gory details...but the pain was awful. I was finally able to conceive 2 children with the help of a fertility med (Clomid) and progesterone suppositories. By the time I was 34 and want to try for baby #3, I was suddenly diagnosed with Premature Ovarian Failure (post menopausal).
I am so grateful that I did seek treatment fairly quickly and was able to have my 2 kids. We later adopted a daughter from China, which is also wonderful
Don't panic yet--just make an appointment ASAP to check out what is going on with you. It could be something very simple to fix.
