Hi everyone,
Looking for a bit of advice and reassurance
I'm 26 weeks pregnant and have put on 26 pounds already, looking at the NHS website it's saying that's what I should put on for the entire pregnancy. 
I stated with a BMI of 25.3 (I'd already put on a few pounds before I got pregnant due to various factors, main ones being quitting smoking before TTC, coming off anti depressants and my Father passing away) I'm 5'5" and 37 years old this is my first pregnancy.
Basically I probably put too much on during the first trimester, constantly grazing was the only way to stop the nausea.
Just wondering what I should do now? Should I start monitoring my calorific intake? Obviously not diet but try to slow down my gain, and try to make sure I don't exceed 2000 cals a day? I feel so tired and unfit, I was fairly fit before the pregnancy (used to jog and go to a bootcamp class, neither of which I do now) and now I feel like I've aged 20 years, it's a 20 minute walk to work (best part of a mile) which I do 5 times a week there and back (but I'm huffing up hill), and I also do pilates once a week. My weekends can be pretty sedentary. Perhaps I should try to take up swimming.
Sorry for the ramble, any advice would be greatly received.
