So we started to have sex an just when I was about to climax he says he can feel baby?!?! I’m like wait what ???? He like why do your stomach look like that??? I’m like what you mean??? I’m 16 weeks by the way but baby was popping out at the bottom of my uterus..... 🤦🏽‍♀️🤦🏽‍♀️🤦🏽‍♀️🤦🏽‍♀️ long story short I didn’t get to finish because he was freaked out.
