Any advice or similar situation?

Hello here's the back story before my question. I'm 24, had my first baby a year ago, was on the pill for 5 months

I stopped bc back in on oct. 25, got my first period since quitting on Dec 29th then didn't get anything in January, the 7th, 8th, 9th, and 10th I got positives on opk tests but during those I had light spotting, so I didn't know if they were ovulation bleed or AF finally arriving. Talked to my gyn about it and he told me to take Provera for 7 days to induce a period, tomorrow (Feb 24) is my last day. He said after the period to start taking my opk tests again to track ovulation .

My questions are how many of you became pregnant after doing this? And how soon? Did up actually ovulate? Any advice or similar story's would be helpful. We got pregnant right a way with our first so this is all new to me.
