I have had 2 c-sections and remember my Ob telling me that after 6 months the scar is fully healed, so since your last one was mid 2009 you would hope there would be no worries at all with this pregnancy and the scar rupturing. Also, I always get really sharp pains when coughing or sneezing in early pregnancy, I was told it is the round ligament of the uterus stretching. Definitely had a few earlier on during this pregnancy, and it is intense for a second then goes away. I would think that if there was any rupturing of your scar you would still be in pain. Of course, if you're worried, ring your Ob or go to the hospy! Good luck, HTH
