Scar hurting 15 weeks pp

bitsybubbles7

Has anyone else had their scar stop hurting to start up again later?  I am about 15 weeks pp and my scar hasn't hurt for at least a month, if not a lil longer.  Now in the last week or so the right side is hurting mildly especially if I'm getting up or down, and occasionally lifting.  I'm wondering if this is normal since I'm getting on the floor more with lo and trying to get more active?... Or should I be calling an ob cuz I popped a stitch?

TIA!!!
