Chemical pregnancies?

I just wondered how many of you guys have had chemical miscarriages? I was so happy to get my BFP two days ago but my tests have now all gone negative, just like last month.. (I’ve tried testing in am,pm..ect so it’s definitely gone), so I’m just sat here waiting for the bleeding to start. I’m completely heartbroken and thought 2 miscarriages in a row was not common and that it was finally our time.I think my stupid body is just broken and should give up now 😢
