Same with me that's probably what it was cus I ate Wendy's that night, & not enough water either. Ibeen trying though
I had it around that weeks but for like a week or so the doctor said it was your ribs expanding to make room for the growing baby, BUT there was no throwing up you should tell your doctor on the next appointment
This happened to me when I was about 21 weeks! I have no idea what was going on and it only happened that one time so I guessed it was something I ate and I just slept weird that's why I hurt so bad. My feet were also super swollen when I woke up so I figured maybe dehydration.
