I've been so sick lately past couple of days. I have a fat head ache and its so hard to eat and keep my food down now. I feel like I did at the beginning of my pregnancy I'm 36 weeks now and feel like poo. its scaring me cuz I know my boy needs all the food he can get these past last couple weeks and I'm having the hardest time with my appetite. Any suggestions?
