Pcos taking prometrium (progesterone) for thin lining. Had a monitored "natural" cycle (only took Vitex) but we did trigger once follicle was 22mm. My cd13 labs from Mon just came back - 146! They just drew blood for cd15 to see if it doubled. I have heard PCOS can increase odds of miscarriage. Anyone experience good betas who lost the pregnancy? It took a year to get here (incl. 4 Clomid cycles and only responded to 2)... obviously ecstatic excited but proceeding with caution...
