My hospital took credit card, but they also didn't remind me to pay, so I had to go back after my blood test when I remembered. I think it was £5 each.
Scary and frustrating @MinervaMouse. As others have said, it can be your blood not the baby's blood that created an issue. Or maybe it's something else. Fingers crossed it's ok whatever happens, hand firmly held for tomorrow.
On the sickness, I've mostly had nausea, gagging or sick in the back of my throat. I suppose that might suit a hangover. What I do with a hangover is sleep LOADS and drink water, maybe eat cream crackers. That's exactly what I've been doing a lot of; sleep, water, cream crackers.
