History of miscarriages

Hello,

Curious if anyone has experience here. I tested positive over the weekend. I’ve had multiple miscarriages but also had a successful pregnancy (he’ll be two).

I am VERY early only 5 wks but want to do everything I can to not lose this pregnancy. I don’t have an OB yet (my old OB retired and the one I used for my last pregnancy/miscarriage was awful). I plan to get something scheduled ASAP but last time I got pregnant they wouldn’t see me until I was 8 weeks.

What tests/precautions can be don’t between 5 and 8 weeks? Anything?

Thanks for any advice/suggestions.
