Two miscarriages and trying to stay hopeful

I’ve had two miscarriages, one in December and another one in March. I was hopeful when I found out I was pregnant the second time and I had heard and read that some many people have one miscarriage and then successfully get pregnant. But after two miscarriages, it’s hard to be optimistic about it all. We did all of the testing and we both came up as healthy with no underlying issues. As we start to try again, it’s also hard not to obsesses about it all. Any suggestions on how to be optimistic after two losses would be really appreciate!
