ttc first baby!

My husband and I have been together a total of 6 years and been married for 3. We didn't really start cracking down on trying until last month I took temperatures and showed two positive okps. Had sex the first day I showed a positive and two days after. I do have pcos and just started taking metformin for it. I've read great success stories on metformin. Does anyone have any tips to help me? Has anyone taken metformin and got a BFP :)
