I am about 25 weeks pregnant , and i am shakey, light headed, dizzy, and kind of nauseous. i feel like im going to pass out even when im just sitting down. i havent had any major issues with this pregnacy (this is my second child, first pregnancy was high risk) ive tried eating, and getting my blood sugar level up but its not that, ive also tried drinking water thinking it was dehydration . its not helping. what should i do? could this be hormomnes or potentially dangerous for me and my baby?
