Getting nervous again

I had a FET in November and got pregnant. At 7 weeks we were told there was a sc but o baby, and I had a D&C. I hav another FET scheduled in about 2 weeks. I thought I would be excited at this point (I have been looking forward to the transfer ), but I am starting to become nervous about this one not going well either. I am also feeling sad, which I haven't felt in a while. I am scared about something going wrong, and it is reminding me of what happened last time and how awful it was.

Has anyone lost a pregnancy after fertility treatment and gone on to have a successful pregnancy in the next round?
