What would you do?! HELP!

Rebecca
I'm 12 weeks 4 days with triplets, I've had a terrible pregnancy since 6 weeks, but was put on Diclegis and a regular nausea medicine so I could function on not have to live in the hospital due to dehydration or lack or nutrients. I'm still not eating much and throw up at least once a week with the medicine, as well as have a raging headache/migraine about once a week. The difference now is that since Thursday mid day, (its now Sunday morning) I've had a terrible headache changing from migraine to dull annoying headache and then back to migraine again. That's about a 4 day long headache. Since Friday morning I've been nausea and throwing up, with only little relief every couple of hours, last night I woke up every hour which I normally sleep through the night other than to pee, and woke up at 7am with the most horrific leg cramp pain in my leg calf. What should I do! Is it normal pregnancy symptoms or a sign of an underlying issue ?
