Paranoid of miscarriage😣

We have a 2yr old daughter and everything about her pregnancy was almost textbook perfect.

We suffered a miscarriage in October at 8-9wks😔doc said nothing I did, was probably a chromosomal abnormality.

I am currently 10w5d with our rainbow baby and couldn’t be happier!! Our daughter loves loves LOVES babies, so excited to give her a sibling😁

However, I find myself worried at times thinking that I should maybe not get too excited in fear of losing the baby😣 we have had 4 scans (6wk, 7wk, 8wk, and 9wk). Each time the baby looks healthy, had a strong heartbeat and grew to the appropriate size or measured ahead.

Losing a baby is traumatizing!! My next scan is a week and a half from now on May 10 when I should be exactly 12wks.

I’m thinking of buying an at home fetal Doppler. Not sure is that’s a good idea to help reassure me off and on until I can start to feel baby moving-or if it will make me crazy and should avoid buying one.

Suggestions?? TIA
