I second Sarah's opinion,,,,as i didnt feel too good until the 6 weeks mark,,,,
But even after 4 years, if i do too much lifting/bending etc now, my tummy gets very sore, and tires out easily (however I do have a hernia in my belly button as well, so that might have something to do with the soreness.)
i am in for another caesarean in mid feb, but am going to try and get the hernia repaired at the same time,,,as well as tubes tied. Kinda like a "while you are under the bonnet, woud you mind giving me the works? lmao)
