first round clomid success?

Kiana
Hello ladies, so my dr. Prescribed my Clomid to get pregnant & I was wondering has anyone have any success with conceiving on the first round. I am on 2 pills for 5 day. On day 3 of my period. Waiting for my period to come (taking medicine for that as well) I will also be taking 2000mg of metformen every day along with prenatal vitamins.. I do have PCOS..
