Fern I'm so sorry. That is a horrible and unsettling thing to happen and I'm not surprised you are so upset. The added security will hopefully help you to cope better tomorrow and in the meantime, maybe try some meditation to let go of the feeling. I use The Honest Guys on YouTube, their guided meditations are awesome for relaxation.
I've booked a reassurance scan on Thursday. The EPAC refused to see me, so I've found a private company that does them near here. It's not cheap, but I need the reassurance right now. The pain has stopped, but I'm still feeling quite anxious and like it's not real again, like I did before the early scan. That scan kept me calm for about 10 days, so I'm hoping the one on Thursday will see me through to my NHS scan at 11-12 weeks!
