PCOS and Infertility

Ever since I was little, the only job that I wanted to do was to be a mom. When Chris and I were first married, we thought about waiting a couple of years before trrying to have a baby but within a couple of months we felt like it was time to have a baby sooner. After a year and a half of trying there was nothing and we did not understand why we had the "feeling" but still no baby. I went to LA Weightloss in Aug 2004 and lost 35 lbs, then in Nov, I went to my OBGYN who put me on CLOMID. In March, the day after our second anniversary we found out we were expecting our first baby that turned out to be the twins. We felt happy and excited and knew the wait was because of the twins.
When we decided it was time to try for another baby, I went on the Clomid instantly since we knew I could not get pregnant without it, and then found out we were expecting in July 2007 and was excited again. But the pregnancy went from just sciatic nerve pain to preeclampsia and the end. In Nov, after Joshua was born, I went to a Family practice doctor about my blood pressure that still would not come down. I was diagonosed with Polycystic Ovarian Syndrome aka: PCOS. It explained that because of PCOS I cannot ovulate on my own which requires Clomid to get pregnant. I was also put on a medicine called Metphormin to control the PCOS symptoms. PCOS also makes you obsese especially in the mid section, blood pressure and chlorestral can be high, irregular periods, thinning hair, hair growing on face and back.
I thought that I finally knew why I have a hard time getting pregant and explained why the need for Clomid. I got the okay to start trying last spring, but in the summer, they found 2 over sized cysts on both overies. So I was put on Yaz and within a couple of months the cysts we gone and I was given the ok to be on clomid in Oct. Well I am still not pregnant 6 months later. Yesterday, I went in for a ultra sound on my overies in the middle of my cycle to see what my ovaries are doing. The tech found 3 folicales there. When I talked to the doctor after the ultra sound, he said that one is too small and the other two are double in size then they should be and most likely are cycts. I will find out in 2 weeks if they are truely cycts. If they are cycts, I have to go off clomid because it will make the cycts grow and I will still have infertility. I would have to go back on Yaz to get rid of them and be on it for a few months before I could go back on clomid.
I can say the I am disappointed and I do not understand this continual trial that I face when trying to have children. I am greatful to have the 3 beautiful children that I already have because with my PCOS, I should not be able to get pregnant.
I pray that I can get through this road block quickly and that a new baby will join our family shortly.
