When people's opinions get to you...

So my appetite has increased a lot recently and when I want to eat it's my baby telling let's fill that tummy up so I can take it all...so my step mom told me told that I will get fat from eating so much. Not only did that piss me off but I have only gained 5 pounds and I'm 15 weeks....I eat just fine but when I'd like a second helping I know it's for my baby and we will be just fine. What pregnant woman wants to be told you will get fat from eating a little tiny extra?!? Sorry I had to rant. This whole pregnancy she has decided that her opinion is law....ugh.....
