Hi ladies,
​I'm 8 weeks and 4 days and am hungry all the time, I even wake in the night hungry.
​I'm worried about my weight anyhow as I'm a bit porkie and just wondered if this is normal? I'm trying to eat healthy and 5-6 small meals a day, but just wondering what everyone else is experiencing?
​I have been like this since 4 weeks, the day before BFP!!
​Thanks
