So I am only 31 weeks..

However lately I’ve been she’s been more calm. She’s already head down and has been for awhile. I haven’t been having contractions that I believe. However, I’ve been having more back pain, mild pelvic cramping, and it radiates to my knees and ankles some times. I still feeling her move here and there.
