Ugh.. Here we go again :-/

We've been married 8 years. I have 2 boys (13 and 9) he has none.. We've been TTC actively off and on since we got married. This makes month 3 of putting forth more effort than ever! (I know not a lot of time there) I'm taking prenatals (the good ones too!) last month we went through almost 10 opk's and 6 pregnancy tests. This past Tuesday AF had her damnned visit. I cried. He cried. So here we are.. AF is over, so when should I start the opk's again? I didn't want to take them with AF lingering around. I'm 30 years old.. I don't feel as if I have loads of years left for this parade again but jeez.. I would LIKE to have a baby with my husband for Pete's sake!
