I am only 6 weeks and morning sickness has completely taken over. I spoke way too soon yesterday about being able to only stomach Mac n cheese because I can't keep anything down the past couple days. I feel so weak and defeated I can't even function and have been in bed all day. I've tried to force myself to eat and drink and it just comes right back up. Today I can count only peeing twice the second time being barely anything. Should I be worried?
