I feel like my abdomen has been weirdly tight for most of the day today. It doesn't really come and go; I just feels tighter for hours today and I feel kind of out of breath if I get active. Is that normal pregnancy stuff? Feels a little like my muscles are sucked in and not relaxing if that makes sense. It doesn’t really go away if I change positions except it feels a little better if I lean over. It went away once or twice today but it’s been most of the hours since this morning. I’m 22+3. I’m just paranoid I’m in preterm or labor or something awful. You know, your mind goes there.
