Diagnosed w/ PCOS 2 months later, preggers?? wahoo!?

So I was diagnosed almost 2 months ago with having PCOS. It was pretty upsetting news considering my partner and I had just decided we were going to start ttc. I had gone into the dr's with sort of abnormal periods and had some bloodwork done and lo and behold my dr. came back with my results saying that it was nearly impossible to become pregnant if you are positive for PCOS. After that, we had decided we weren't going to try anymore due to the news and also because we had given ourselves a timeline to stop because I am the maid of honor in my best friend's wedding next June. My periods the last couple of months had gone back to normal then I had noticed it was about 1 1/2 week late and started having just really odd cramps. I decided I would buy some hpts just to prove to myself it wasn't going to happen for me and they all came back positive!! My dr. told me that there are no risks after getting pregnant with PCOS but my mom had gotten me a book about it and stated that women with PCOS have a greater risk of gestational diabetes and miscarriage. The nurse that I talked to this morning told me the same thing the dr. did. I had them send a lab order for bloodwork to be done to check my Hcg level to make sure things looked as normal as we can see this early on. From what I determined I'm about 5-6 wks along (first day of last period was 9-9-10) I'm hoping to hear back with my results today. What all will they be able to tell me from this bloodwork? Normal hcg level for what week I'm in? get a better idea where I am in my pregnancy? Anyone else diagnosed with PCOS and wound up pregnant right after?? lol we are very happy but cautiously nervous parents. Thanks!
