Ever since I was younger, I've slept on my stomach. Lately, it's felt really weird to do that (this past week). It almost feels like it did when I was pregnant with baby #1 and I rolled onto my tummy at 20wks preg. But I'm only 11 dpo and I took a clear blue digital today: bfn. Not constipated either. I know I'm not imagining this, but what could it be? There's no way this is an early preg symptom is there? Or maybe it's because I've put on 4 lbs?
