3rd pregnancy

Racheal
Hey ladies. I am trying to get some insight from woman that have had multiple C-sections. I am ttc my third and i was wandering if/ when did your C-section scar start not hurting but feeling uncomfortable. I had what i think was my period (and i say think because it was really short and very light for me i only spotted) on the 3rd-6th and i believe i ovulated the 14th -15th . well i woke up this morning with my lower back hurting and my lower abdomen (around my scar) is sore, so if anyone out there has dealt with this please give me an idea what might be going on also since i ended my period its very uncomfortable to have my pants buttoned they still fit but just uncomfortable.TIA
