So confused..

I have pcos and came off the pill 50 days ago and have yet to ovulate or have a period. A couple years ago i went pill for 3 months with no period.. my dr wants me to take provera and then if i dont ovulate in another month take it again and then try letrozole.. Im just worried about all this medical intervention so early in ttc. I am 28 and really want a baby and the not knowing/waiting is getting to me. Ive heard mixed things about fertility medicine. All the talk of failed attempts, misscarriages, health problems scare me. I dont want to wait year(s) to get pregnant naturally. Any advice?
