weight or fluid retention always shows on my face first though i would mention it to midwife as you should always tell midwife about any puffiness or swelling you might have just to be on the safe side as deleting said
it might be just water retention. i am 20 weeks and mine looks much fuller already. i retained a lot of water during the 1st weeks of pregnancy, though. it did get better after a while. try to stay away from salty and sugary foods. if you practice yoga, do inversion postures - really helped me.
I look like a cross between Jabba the Hut and Slimer out of Ghostbusters. I have read that it is normal to put on weight particularly around your face in pg. It sucks I know, but I think it is normal unfortunately. x
