It is possible that you are pregnant and it's just too early to tell, or it's also possible that your hormones are still out of whack since your m/c. I had an early m/c in September and about a month later I experienced nausea (to the point of retching) and I was very emotional/hormonal. I thought I may be pg again, but I wasn't, it was just my hormones settling down.

I have my fingers crossed that you are pregnant again .
