Conception after several miscarriages

Hey all, I recently found out that I am pregnant. This is my 4th pregnancy. I have one child. I have had two miscarriages, without a reason as to why. *miscarriages resulted in D&C’s.

I am seriously considering not calling my doctor until 8 weeks.

It confirms in my head that I am pregnant after seeing a heartbeat, which I have done every time, only to find out baby’s heart stopped at 7+4 and 7+5.

Am I being unreasonable? Thanks for any advice.
