I am so sorry to hear about your losses. But this thread (as many others on mumsnet) were a lifeline for me going throught he same experience. So I thought I would add my process here in case someone else googles this info as I did.
Day 1:
12 week scan - found out baby heart stopped at 8 weeks
Up to that point I was getting some light brown discharge, very minimal
I decided to do the Surgical management.
In that same evening, i started feeling cramps, like period
Day 2:
Hospital told me I had to be rebooked for the afternoon as emergency had other priorities. As my cramps were still happening, I decided to go home and see if everything happened naturally. Which it did.
8pm: Flush of transparent liquid came out
10pm - 6am: constant trips to toilet, with pads being filled every hour, then flushes of blood and sounds of clot being dropped in the toilet. At that point I was feeling very light headed, and having hot water bottle was really helping with the pain.
6am - 10am: cramps became contractions, still bleeding but pain was getting really hard to cope
10am - 6pm: cramps stopped. But I still had a feeling it wasn't over. Feeling very tired as well, but took time to rest.
6pm - 10pm: heavy contractions again, really painfull and almost constant. No bleeding. Then in the end very strong pain, went to toilet and pushed a bit. Something came out, I couldn't really see anything, but there was a relief feeling straight away. All pain was gone and I felt a bit shaky.
Hospital told me to go A&E if I was bleeding too much, which means feeling 1 pad per half an hour. So thought it was a good information to share as well.
I was glad everything happened at home, but I had the full suport of my husband.
Although it was super painful process, I do feel it helps to heal and recover from the trauma. As you feel it by every minute of the experience.
