@MummytoMatildaX sorry for the belated reply.
I'm doing fine now, thank you for asking. I have two kids already and this was not a planned pregnancy so I was doing lots of things 'wrong' (not suggesting any of it is your fault, just for context).
Based on what you've said I would prepare yourself for a miscarriage, yes. I had a positive pregnancy test at around 5 weeks pregnant then started cramping and bleeding around 7/8 weeks.
it started with some cramping and dark brown spotting then developed into fairly heavy red bleeding. I went for a scan at the EPU and there was still a heartbeat and they said the pregnancy looked normal but it was much too small for dates. It looked like a 'normal 5/6 week pregnancy'.
Like you I was certain about dates so I knew that couldn't be right.- at this point I actually booked myself in for a termination because it was clear that it wasn't really a viable pregnancy, but they couldn't confirm when I would miscarry and I was terrified that it might drag on for weeks.
At the pre-termination consultation there was still a heartbeat and an embryo, again measuring much too small for dates. However, over the following four or five days, the bleeding and cramping got worse, and I went back to the EPU and was scanned and they confirmed that the pregnancy had passed and there was no longer anything there.
The actual miscarriage happened naturally and was not too bad an experience. The pain was no worse than moderate period pain, the bleeding was fairly heavy for a few days, and the worst of it was really not knowing what was happening. I was pretty sure when I actually passed the pregnancy because it felt like a very large clot but there was nothing visible or traumatic to see.
Once the hospital confirmed that it had all happened naturally I felt very relieved because I knew it wasn't right from the start.
I'm really sorry that you are going through this, and I hope that it all resolves for you sooner rather than later, one way or another.
Please feel free to ask anything else if it would be helpful for you. All the best
and probably
