For those who had a chemical, when did you start bleeding?

I’m sorry if this is a sensitive question. I think I’m having a chemical pregnancy but haven’t started bleeding yet. My period is 5 days late. 5 days ago I got a clear positive test. The next 2 days I got very faint positives, then yesterday and today I got negative tests. The only times I had sex in the last couple months were Sep 28th and Oct 3rd, so I couldn’t possibly be more than like 5 weeks. I haven’t been to the doctor yet, I’m calling first thing tomorrow morning. I’m still having pregnancy symptoms and none of my usual period symptoms, but no blood or even any spotting yet.
