My belly got low already, however, for some reason it's still hard to breath...

@mommy31996, )))) cannot imagine carrying twins!!

Its normal, baby is taking up a lot of room in there and pushing against everything, so you'll feel like your not getting a big enough breath. I felt like that with my daughter towards the end of my pregnancy and thats what I was told, currently 19 weeks with twins and Im already feeling like that lol
