26 weeks with bad pain

Hi everyone, so i’m 26 weeks pregnant, and for almost two and a half weeks now I have been having some pretty bad cramping that disturbs my sleep. I have only ignored it because I know round ligament pain is common through out pregnancy. But a few nights back i had seen some blood when i wiped front and back and it was mixed with some clear discharge so the blood looked pink, sort of. & this morning I had morning sickness but i threw up blood first and than the nasty yellow/green vomit (i’m sorry tmi.) & now when i was in the shower I got a SHARP pain that didn’t allow me to move for a good second on my left side. Can anyone give me advice? my SO wants us to go to the hospital, but I want other mommies recommendations and advice first. thank you.
