Hi, (popped over from the 2nd trimester....)
I had an m/c at 7-8 wks in August 2009 and, while it took me another 15-18 months to conceive again, I am currently 17wks+2 days....my GP and m/c counsellor said that the majority of women do conceive again and have a healthy pregnancy/baby -- I certainly hope so!
My DH and I had decided to do IVF and in January of this year, began the blood tests, scans, etc., I also have PCOS and after a very late cycle (possible chemical pregnancy?) in September 2010, my GP put me on metformin. This January, it was realised that my thyroid was underactive and was put on low level meds; I also did acupuncture (whether it helped or not, it did relax me!) and saw a consultant ob/gyn for scans 'down there', and went to a fertility nurse/specialist in the UK; in May of this year, I had my pre-IVF first cycle bloods and my thyroid was still slightly underactive, my meds were increased and I had my first 28 cycle in months; I got pregnant naturally the next month and am due the end of February. I am so 43, so know that my odds of getting pregnant naturally were quite low, but so far, all scans, bloods show a perfect little baby boy.
So, yes, it can happen -- many of you are probably younger than me, but I also lost weight and quit smoking in Jan-March (it took awhile)/pls note -- did not smoke when was pregnant last time, but started again when it was obvious was having an m/c. I think, in my case, the underactive thyroid was the final 'key' in getting pregnant and I believe that the continued use of metformin in pregnancy may have helped the blood flow/placenta formation (see some studies which support, others disagree). Personally, I am still somewhat shocked that I got pregnant again, but very cautiously hopeful that this time it will be ok.
best wishes
