Taking second round of Clomid and not sure when to have the most intercourse?

Kaela • I`m a 21 year old woman who is now trying to have a baby! I have to take clomid to help me ovulate due to Endometriosis and irregular cycles. Hope it helps! (Just started it)
I started taking 100 Mg of Clomid on 1/22/14 and I take it for 5 days. I'm just wondering when will I be the most fertile and when to have intercourse? I'm 22 but I've been on the depo shot for a few years so I'm not sure how many days I give the Clomid before we start having lots of intercourse.
