I had this at 12+6, the day after I'd first seen my baby at the 12 week scan. It was 3am, the world was asleep and I popped to the bathroom for a wee and when I wiped, I was convinced I was having a miscarriage - especially when I saw blood dripping into the water below.
I tearfully got a sanitary towel and woke my DH and told him "I'm losing the baby" and we called 111. They advised me to go to the Early Pregnancy Assessment Clinic at our nearest big hospital, 45 minutes drive away, but they wouldn't be open till 8am. We were waiting outside in the car park from 6:30 and I felt like such a failure - it was as if I had been too happy the day before when we'd had the scan. Like I'd been too proud when I showed off the photos to my colleagues and announced my 1st pregnancy on Facebook the night before. And now I was going to have to tell everyone I'd lost the baby.
I was in the same waiting room, waiting for the EPAC scan as I had been for my 12 week scan the day before, luckily we were the first there. The Ultrasound Technician was very calm and caring and just replied to my panicked gabbing with; "Let's just have a look and see what we're dealing with, shall we?"
I lay on the bed and not 20 seconds had passed before she turned the screen round and announced; "One lovely strong heartbeat!" I'd never felt so relieved in my entire life.
So a subchorionic haemorrhage - something to do with having a low lying placenta in my case, I think. Happily, everything shifted about over the next 6 months, I had no more bleeding after that episode and that "baby" turns 12 next week and she's marvellous!
Put your feet up and rest OP, it's horrible and scary, but you know what it is and the Midwives will keep a close eye on you and before you know it, baby will be here - I wish you the best of luck with everything!
