My luteal phase is fluctuating between 10-13 days. is this a fertility issue that can be treated? i am trying to conceive over a year now .

Yes: At 36, you should see a gyn immediately. If you are having a short luteal phase, the embryo will not have time to implant. Sometimes taking Clomid (clomiphene) can correct this. Sometimes taking Progesterone can correct this. I had a long struggle with infertility and was amazed at how complicated it was, even for a gynecologist.
