Heading back to the ER

I am having the worst time ever. I started bleeding on Monday, went to the hospital. Had an ultrasound Tuesday, twins, gestational sacs measuring at 5 weeks, 3 days and 5 weeks. Said no cause or worry for bleeding. Bleeding a lot more now with cramping, it's not looking or feeling too good. I've never been so upset, I've never wanted anything more in my life. Praying to God they are okay.
