Will of course discuss with my midwife, but wanted to get some real life stories / experience from you all if that’s ok 
I’m 20 weeks pregnant this week with first baby - but have put on 2lb from my pre pregnancy weight. I was pretty average before pregnancy - not slim but not overweight - and fairly fit. But had a pretty sicky first trimester and since then heartburn has me eating little and often rather than full meals.
I’ve been trying to walk a couple of miles everyday to keep fit and eat as well as possible.
However - I have read that by 20 weeks expectation is to have gained more in the region of 8-10lb. I guess everyone is different, but did anyone else find their weight gain slower than this? And was there any concerns for baby?
Thanks so much!
