I had an appointment 4 days ago and was measuring a week and half head I’ve been measuring bang on up until now. I’m 36 weeks and measuring 37 1/2 but today I took out the tape measure from my book they used an I’m now measuring 41 weeks and half so I’ve gone for measuring 37 1/2 to 41 1/2 In just 4days? Has this happened to anyone else ? Should I get checked just incase?
