What are the chances?

I was diagnosed with pcos in may of 2010.. since then i have been prescribed provera 10mg taken for 7 days the third week of the month, to induce my period as i dont ovulate, just this august i was prescribed clomid 50mg taking on cycle days 5 to 9.. between September 14 to 19th, I was suppose to take ovulation test to see when i would ovulate, those tests are soo confusing, it tells you several different things about the 2 lines, and not thinking about it on the 16th and 17th of this month I had 2 lines,which im uming indicate ovulation, cuz i had left side cramps for days before that.. my husband and I had before that and the Saturday after, is there a good chance that I would get pregnant this month, as i took the clomid and the provera last month and have not taken any of the meds this month.. I got bloodwork done this morning to test my progestrone levels, is this the doctor trying to see if we succeeded in getting pregnant?! I guess with my medical background, I feel i have to research and look into things when it comes to something like this, has this ever happened to any of you?! Has anyone ever been in this situation and found out they were pregnant first time around, as I will be unable to try for the month of October because I have not taken any of the pills this month.
