Yes, it can be difficult Mel.
My first mid tri loss (B0b) was at almost 16 weeks but our daughter had died about 10 days before so it wasn't possible to tell gender until the path reports came back. I had a D & C as she had passed away some time prior to the u/s.

My second loss I birthed and he was born after a long 14 hour labour and it was clear he was a little boy. At 14 1/2 weeks babies are too big to be taken by D & C but I was glad to have given birth to him.

Eggbert was my earliest mid tri loss at 13 1/2 weeks and I had to wait to find out as you know from path as I also had a D & C.

My two early losses of course I will never know as they were at around 5-6 weeks.
It does help to know that Eggbert was my daughter, and I do always wonder what sex my early losses were.

I have sadly found from experience that once the sex is known it does help to have a little closure.
