Weight gain/loss

Michelle 🇬🇧
My weight is like a yo yo! Pre pregnancy I was around 134/135 then I went up to 139 in a cpl wks, then my sickness and smell aversions cut my food way down to fruit and crackers and I went down to 133, today I'm 135 it's up n down so much! I'm 5ft 6in so not to small or to tall but today my thighs look quite thin and I thought uh oh lol so I've had a larger meal today of baked potatoes X 2, cheese and salad and my god did I struggle to keep that down! But I did, so hoping I settle soon and can eat normally (8wks 4days right now)
