I'm really so sorry to hear about your loss, Lucy. I have also been in your position (ruptured tube, internal bleeding, surgery), so can completely understand how awful and worrying the entire experience and aftermath is.
My DH and I had started trying for a baby but I didn't know I was pregnant at the time. So, to say that it was a shock would be an understatement (sudden pain/collapse, hospital, pregnancy announcement, surgery). What I found most difficult was that, after hospital, everyone was focusing on my physical recovery (which I guess is normal as is an easier subject to talk about than the loss of a baby and unknown impact on fertility), whereas I was feeling so sad and numb about losing a baby - as well as a general fear of what losing a tube meant. I had a lot of anger/sadness. It was hard to explain how I felt - I felt very alone - and it took me quite a while to feel like I had recovered emotionally. I also hated my scar, as it was an ugly reminder of what happened.
Like AitchTwoOh, I also spent time on the Ectopic Pregnancy Trust boards, looking at other people's stories and trying to get to grips with what happened in my mind. I definitely found the boards useful.
This was over two years ago. Afterwards, I put plans for TTC on hold as didn't feel ready, but started trying again last year. I was scared about losing the other tube, and being strong enough to go through another ectopic.
After 3 months of TTC, I fell pregnant and am now due in September. The early pregnancy unit at the hospital were brilliant, and got me straight in for early scans as soon as I had a positive pregnancy test result. I actually had three scans (first it was too early, then they saw the sac, and the third scan, the heartbeat) and felt very well monitored throughout the process at the start.
Please take your time. Don't rush to get back to normality if you don't feel ready. But above all, please be kind to yourself xxx
