Hey all! FTM here. Starting to worry a little because all day my legs have been super sore. I used to get this feeling before my period would start it would be my first symptom. My legs would ache and be so sore. Now I'm 22 weeks and have had no cramping lately but having these leg aches and soreness is worrying me. It's my first time experiencing this in my pregnancy. Is this normal? Thanks in advance!
