I'm due 13th March. Got weighed and have gained 20kg!!! I have been eating large portions but always healthy food, just maybe to many carbs. Midwife said baby is in great position and head engaged. I am 5'9 and she kept saying 'you know you're not going to have a small baby don't you'
I am now stressed I am growing a monster size baby! She proceeded to tell me about a 12lb baby she delivered a few weeks ago 
I am meauring 37 weeks at 36 + 3 so not overly large. I just wondered with the head being so low does that stop my bump from measuring large? She said I didn't need a growth scan as measurements are fine.
Hoping you can reassure me.
Thanks
