Being uncomfortable on my stomach was one of the first signs for me that I was pregnant. But like you, I'm a belly sleeper. I am not comfortable unless I'm on my belly if I'm sleeping (on my side is fine if I'm just laying down.) I sleep in odd positions too - it looks like I'm doing yoga in my sleep at times because I'll go into the "frog" kinda position and sleep with my legs underneath me. Which worked for a while. But now my belly's gotten a bit bigger and higher, that's uncomfortable too! The only way I've been able to sleep this past week is if I have all the pillows (so I have to wait til DH is out of bed before I can steal his) and have them doubled up and propping my upper body into almost an upright position with my belly hanging loose and only my legs on the bed. If DH is in the bed, I've been using him as an extra pillow Though I still can't sleep properly with him in the bed, it takes some pressure off. He's getting annoyed that he keeps waking up with me snoring half on top of him
