Pregnancy is an amazing diet for me, mostly I think my metabolism must speed up but the I'm sick too so can't eat as well as I would normally. You will be fine.
My first I was 3 stone lighter full term than pre pregnancy and baby weighted 9lbs!!
I lost weight with my first wouldnt mind loosing a little this time around either! Like you im going to the loo a lot, I think swapping the energy drinks and fizzy pop for water might help x
Wow 4 cups, haha have you tried the decafe? Im on my way out for tea with my friends so ill be treating myself to a coke I still cant believe im pregnant and we found out the same day x
