nervous and can't wait!

Hey guys I'm really getting anxious to find out if I am pregnant after my first round of Clomid. I'm due for my AF on the 14th of this month. I'm having a hard time getting pregnant not sure if it's due to my age or my past life style of smoking and drinking. I'm turning 37 this January.. Beginning to think that I can't get pregnant. Or I have no eggs left. So worried. I have gotten pregnant a few times in the past but I was in my addiction and wasn't ready so I know I am able to get pregnant but now that I am ready and married it's just not happening. I just order fertillaid from Amazon for my husband and I. Has anyone tried fertillaid and does it work?
