Hi - I have just had an early mc at 5 weeks on clomid, my doctor quoted some stupid % figure of women who mc on clomid - don't know where he got it from but I had a look on net and it seemed not that much higher than the average % of pregnancy's that end in mc, before 8 weeks. I know clomid can stop your womb lining from growing and that this can be a problem with implantation but I think clomid has little effect on mc after 8 weeks, when baby fully attached into womb.
hope this helps, Noodles
