oh buliej, my heart breaks for you...I am so sorry, and of course, know exactly what you are going through.

to answer your questions....
I felt pregnant...sore, larger boobs, swollen tummy etc and that lasted until I had the curette, and then afterwards, those things slowly returned to normal, which was a relief, because I hated having those physical reminders of the pregnancy.

After the curette I had period like cramps and lower back pain...for about 5 days afterwards. I had bleeding, lighter than a period for almost two weeks (was told it could last for 10 days). But by the end my body had returned to 'normal' feeling.
I also had the tissue sent away for testing to confirm there were no abnormal placental cells, and there weren't, so that's a good sign it was just the embryo not developing as it should, and that there was no bigger issue.
My clinic told me to wait until I have my next normal period before starting IVF again.... then because of the xmas break, said that by the time I do get a period it will be too late to start a new cycle...so we will start a new cycle in the new year. In the meantime we are focussing on being fit and healthy, TTC naturally in hope of a miracle and trying to focus on life together and finding joy in the moment. Plus grieving. You can't underestime how hard this is buliej, especially after having gone through IVF to get there etc. On so many levels it is painful and a loss. I felt sad, devastated, but also angry, bitter, resentful. I still feel those things, but they are less raw, and I am also managing to feel hope and have moments where I once again find joy in life and activities etc, and it's a relief to be in this place now, because the way I felt in those first weeks was so hard. But you need to go through that, you can't rush through it, or bottle it up, because it will come back to haunt you later.
Also, it's tough because most people don'tget it, they cant understand what it's like, so the level of sensitivity you need isn't always there.
I just send you the biggest hug. If you need to contact me further send me a PM. I am always happy to talk. I will be away for a week and off the computer from this sunday.
Also, my DH has been most supportive, but he has dealt with this differently to me, and I think it helps knowing that men handle it differently to us and accepting that too.
I am just so so sorry you are having to go through this.
