Symptoms after miscarriage?

Sugeith • Married 11/22/14 and pregnant with our first baby due 12/23/15
I had a miscarriage yesterday at 4w6d, there were some cramps and some heavy bleeding yesterday but today there hasn't been much bleeding but still having cramps, I'm lightheaded, nauseous, have a headache and my blood pressure is a bit high. Anyone else have similar symptoms after the miscarriage?
