pregnant after csection scar pain

mommas who hace been pregnant after csection; i had my daughter via csection aug of 2016 im now 10 weeks pregnant, so babies will be almost exactly 2 years apart. lately my incision/scar had been like a twingy/burning type pain, also when i touch it (i noticed when i was drying off out of the shower) is it normal? or something i should make an appt for? i was suppposed to go to my IOB appt yesterday, but they called me last minute to reschedule and dont have any openings until after the new year. thanks!
