Provera question...

[Four2Five]

So I have to take Provera to "jump start" my cycle every month or I don't get af. I also take Clomid after I start af to help ovulate. The Provera is taken for 10 days which then takes another 3-5 days for af to show. I'm really confused on when to start taking the Provera for a new cycle, since I don't want to take it during my 2ww phase right? I mean in case I am pregnant. So do I start af on the first day of my missed period, this dragging my cycle out to 40+ days? Or do I start Provera during my 2ww so that I can keep my body in a 30 day cy?

For background:

CYCLE 1
Provera Nov 19-23
AF Dec 1-5
Clomid 50mg Dec 4-8

CYCLE 2
Provera Jan 3-7
AF Jan 14-20
Clomid 100mg Jan 17-20

CYCLE 3 ???

Oh and when I used to have a regular cycle my cycles were around 31-33 days and I seemed to O around cd16
