I was diagnosed with pcos in June of 2006, put on glucophage, and got pregnant in Sept. 2006, (I think, you know how cycles can be). But anyways, I had LOTS of spotting in the entire first trimester. I went in too early for anything to be detected on u/s as well, which is scary. But I think the first round of spotting lasted about 12 days straight. And I had some heavy red spotting once or twice. Everything ended up ok...so it can be normal I think. Also, if the spotting goes away, then comes back, you may want to get doc. to check for yeast infection. That happened with me at 10 and again at 16 weeks. Good luck to you, but I think everything sounds great so far
