I am freaking out a bit because I am nearly 16 weeks and have gained a stone already. I know everyone is different but everything medical or official I read says this is too much and I am a bit worried. I have not been working out as much as pre pregnancy but still about 4/5 times a week. I haven't been as strict with the diet but not been scoffing down shed loads of junk or piling my plate up or anything like that.
