Severe cramping and High risk

Hi guy, I called my doctors office already to see what they recommend but it's almost 3 am and who knows if they will get back to me tonight. I am concerned about my severe cramping.  It started about and hour ago and I was asleep when I was woken by the pain.  I am battling heart palpitations and high blood pressure and have been deemed high risk.  Tonight about 8 hours ago my Hubs had a argument. The cramping in scaring me I've never experienced this before. I am 15 weeks should I be worried? No bleeding but this week has already been traumatic with falling and breaking my wrist and ankle.  Please help!
