ADVICE ON TRYING TO CONCEIVE

Monet
My hubby & I have been married almost 3 years in September & have been having TTC well actually lets say not being cautious & out of all these years nothing has happened. He has a daughter prior to me (16 years old). I have no children, but one pregnancy & I'm starting to get worried. I've had a test done to make sure there's not blockage & this morning I was expecting my cycle, but hubby wanted to be intimate so we did & it came down immediately following. He's grossed out by my cycle & I've heard cousins of mine who got pregnant right at the beginning & ends of their cycles. I'm wondering if this will work. Does any of you ladies have advice???
