I’m currently 16 weeks pregnant and have had bleeds on and off since 6 weeks. The hospital sent you home because there’s nothing they can do for you there tonight, they won’t have the facilities available to scan you and check that the baby is ok, so unless you’re in agony or gushing the very best thing for you is to be at home.
I know that’s suboptimal, but the truth is that they can’t do anything to help even if you are miscarrying aside from provide pain relief.
Even when I had a huge gush at 12 weeks, was blue-lighted to A&E for losing consciousness and was filling pads I still had to wait for EGU to open before I could be scanned.
What would be awesome would be an out of hours EGU at all hospitals, run by midwives - but the NHS just don’t have the funds to provide services like that.
