I was diagnosed with pcos in 2003. I always had irregular periods and a few ruptured ovarian cysts. I was told I didn't ovulate and if I did, it was impossible to know when thus making conceiving hard to do. I was 19 at the time so it wasn't an issue.
I had been prescribed 1000MG Metformin in June 2007 but only took it a couple months before stopping due to forgetting to take the pills. For me, the side effects of Metformin (nausea, diarrhea, low BS) lasted only a few days but it worked wonders in my regulating my cycle and helping ovulation. It basically gave me a real period vs. irregular bleeding.
After getting married in May 2009, my husband and I decided to start TTC in December 2009. I saw my Dr. On 12/2 and got a prescription for Clomid to start on day 3 of my cycle whenever it would start. On 12/3 I began easing back onto the Metformin with 500MG. On 12/5, I started spotting. My dr told me that ANY kind of bleeding (spotting or otherwise) would be considered "day 1". So, on 12/7 (day 3) I began taking Clomid with the Metformin.
The next week on 12/16, when I was ovulating, was hell. My body hardly ever ovulated and now with fertility pills I was ovulating A LOT. I had nausea, dizziness, and headache. Took ovulation tests so I know I ovulated.
On 12/25 I was feeling really tired and went to bed at 8pm which is weird being it was Xmas. I woke up around 1:30am with hot flashes and chills, upset stomach, and nausea. I thought I was getting the flu. I was still taking Metformin and quit after that day until I found out if I was pregnant. The earliest I was able to take a test was 12/31. Around 12/28, I started getting this feeling I was pregnant. I couldn't hold out any longer and on 12/31 at 1:30am I took a test with a VERY faint positive! I waited a couple days and on 1/2, got a very clear positive. We welcomed a baby boy in September 2010.
Not sure why but as soon as my body recognized that I was pregnant, I couldn't handle the Metformin. Not even the 500mg that I was taking (half my original dosage). I stopped taking it while I was pregnant and am just about to begin it again. I just love how it regulates me and helps with pcos related acne breakouts. It's a miracle drug for pcos!
