Am 23 weeks pregnant. Suffered with HG until 18weeks so I know how being ill feels. Now I am better and wanting to do things. Go shopping, do cleaning, bit of decorating.
Every single person says something along the lines of "are you sure you should be doing that?" "you shouldn't be carrying those bags" "you can't decorate in your condition"
I just want to yell STFU! Really! I know my own body, I can tell if something is too heavy or I can't do something so stop telling me I can't do things. 
Rant over.
