Hi - have found out we are expecting our 4th. Am 40 and not as slim as I should be (about 3 stone overweight). 7 weeks ago I was losing weight, running and able to suck my tummy flat. Also had just got from a size 16 to a 14 again. Already impossible to suck anything in now - and having that familiar all day nausea like a constant hangover. Here we go again! More nervous this time because starting from a heavier weight and older...any reassurance from you folks?!
