I know what you mean..I'm expecting my second child and first was an emergency cesarean.
This time when I sneeze it feels like a contraction! I've started to slowly get the feeling back near to the cut. So maybe it's just extra sensitive.
That happened to me with my 2nd pregnancy it went away after awhile it took my body time to adjust to being pregnant again. But with my 3rd. Haven't had that so far
Does the pain get worse? Because i mean im bearly at 9 weeks and already feeling it lol i cant imagine when im farther along not to mention i got pregnant exactly one year after my first baby maybe it hasnt healed completely
