what next?

I’ve had 2 miscarriages at 7 weeks and 1 chemical. Saw the heart beat on both miscarriages. Then by second appointment the babies no longer had heartbeats.

I’ve done all sorts of blood tests and everything came back normal.

I did the SHG (Saline infusion sonohysterography) yesterday and she said everything is normal there too. Idk what to do. I asked about chromosomal abnormalities testing for my husband and I. But does anyone have any advice on what to ask for next? Really wanting our rainbow 🌈
