Hi Nikki,
I had never been a tummy sleeper until i found out that i was pregnant, and then all of a sudden it was the most comfortable position for me to have slept in.
I think this continuted until about 12 weeks and then i found that it was less comfy.
Did you tummy sleep with your other pg's?
I dont know whether you should stop, but my OB said that if i was comfy (this was at 8 week appoint) to continue until i wasnt...
hope this helps
