Just incase anyone reads this - an update on my experience. It has a positive outlook but I've been constantly anxious for 6 weeks!
The bright red bleeding at 6 weeks tapered off and had completely stopped in two days. I had an abdominal scan and we saw our embryo's heartbeat - it measured 1.8mm.
A week later I had an IVF scan. They insisted on the internal scan. The embryo was then 9.3mm and I heard its heartbeat. I was thrilled - walked to Asda to get a photoframe for my picture and I bled again. This time more heavily - it was very watery. I went home - on the doorstep there was another gush of blood. This time dark, deep red. There was a dark red, jelly-like clot the size of my thumb.
I thought it was the same as before. I called EPU. The bleeding was heavy again the next day with mild cramps.
We went to EPU - 2 days after our scan at the clinic. I refused an internal scan so they had to do it abdominally. There was a heartbeat. They said the embryo was measuring 9.1mm. By now I was obsessed with CRL references and I knew my embryo shouldn't have shrunk. The midwife wasn't concerned, but I was.
3 days after my second bleed at 7 weeks, it tapered off to brown water and then stopped altogether.
I told my ivf consultant and she asked how deep I was putting the progesterone - I told her deep - the aplicators and instructions said so. She told me an inch and a half would be fine. About the length of my finger.
Since doing this - I have had no more bleeding (now 13 weeks). I spent weeks paniced that the baby was smaller on the second scan, searching mumsnet, looking at miscarriage reassurers.
At 11 weeks my pregnancy symptoms improved. I thought perhaps a sign of a missed miscarriage. I've read every story on missed miscarriages that the internet can offer.
I suffered a particularily painful bereavement of a close family member at 12 weeks. I worried what that would do if the embryo was still going.
And at 12 weeks 4 days I had my dating scan. It was difficult, I couldn't imagine life continuing after the death of a family member. But there on the screen was a little baby rolling around and waving at us. And it was perfect.
