Pcos, Pregnancy & Child Birth A 3rd Time?

Hi to anyone who checks this out!!!

I was diagnosed with PCOS in 2003. Was placed on Clomid and Metformin for about 9 months and found out I was preggers (with my NOW 2 year old son) on July 29th 2004. My Obgyn put me back on Metformin after I had stopped breastfeeding my son when he was 15 months old in 2005. I had only taken it for 3 months. I noticed that while JUST taking the Metformin my cycle would be on evey other month around the hoildays.

In Late September of 2006 I found out that I was pregnant again with my second son born May 19th 2007.

With both prenancies I had Diabetes. My blood glucose was elevated higher with this pregnancy than with the last. I had also more weight this time around too.

Knowing that there are medications and treatments for both PCOS & Diabetes and know what I need to do regrading weight loss, I am still having my doubts about having a 3rd child.

Any advise?
