Anyone else experienc this?

I have felt sick for three days now, i have been drinking tons of water and taking tylenol and beyond exhausted. Like sleeping and waking up completely exhausted. Baby girl has been active but not as much, i have had cramping for three days, on top of back pain, a massive headache that water & sleep& tylenol won't take away, and everything i eat even when i take my zofran, makes me sick and i fight throwing up, and now i am experiencing diarrhea. Like in a 3 mins span of time i had to run to the bathroom twice.. please tell me im not the only one dealing with this... im just so over this feeling..
