Has anyone used metformin and yasmin to get pregnant?

I have been diagnosed with suspected pcos..I had a miscarriage last october,(i was on metformin 500 mg twice a day for less than a month n i got preg) had a natural period in Dec-Jan, then nothing till April 10,this year..since then i am having heavy flow. I went to doctor she gave me yasmin for 2 months to stop my flow and regulate my cycle and shes put me on metformin slow release 750mg twice a day. Has anyone gotten succesfully pregnant when taking these medicines together. Also, did anyone expereince spotting when taking yasmin throughout the first n second pack..i will appreciate all ure advice since i really want to be pregnant. Also, how long does it take to get used to metformin as in no nausea
