I am 14w with DC2 and constantly convinced something has gone wrong. I either have aches under the (already huge) bump, stabbing pains in my side, period style pains in my back or normal backache.
Is this just my body going "oh no, here we go again"?! Fwiw, my first pregnancy was fine except for some backache, I got some spd during labour but that was it.
Presumably carrying 18mo DD isn't helping, but I really am trying to do that as little as possible!
