16 weeks tomorrow.

Brandy

I am about to be 16 weeks tomorrow and have a couple questions. Can i feel the baby in my tummy by this time? Because i feel this pressure in my back sometimes that goes away in a matter of seconds. Also I feel like im getting gas bubbles but i dont have to fart lol. Im mainly worried about this pressure in my back lol. Im also getting this migraines that are brutal. Light and noise make it so much worse. Any suggestions? Thanks in advance!!!
