The only other weirdness I noticed is an increase to my CM (that started when the loose bowels did. My BHs have been getting painful as well.
Should I assume this is a bug or something more?
I'm not sure but my OB told me dehydration can cause contractions/crampiness. Try to keep hydrating and see if BH calms down.
I had loose bowels during contractions - like I was having contractions and stomach problems and thought it was something I ate, then when I went to the bathroom I didn't feel better. I delivered the baby about 24 hours later - I had contractions all day.
