Newb TTC (1st time)

Newb here TTC for the 1st time. How many DPO do you and your partner BD? Do you use OPK's, BBT charting, etc. to tell when you are ovulating? I was on depo for 7 years and came off of it 2 years ago. I still have not had a period, so idk when I am ovulating. My doctor has given Provera before, but it did not work to jump start my cycle. I start round 2 next week. Any advice?
