Has anyone had a chemical pregnancy ??

I found out I was pregnant October 8th and started bleeding for 5 days on oct 15th. I went to the doctor and they said it was a chemical pregnancy. They said I should ovulate in a couple weeks which was falling right in line with glows prediction. So I’ve been trying again. I’ve been taking several pregnancy tests because AF is due tomorrow but they’re all negative. I’m so confused. They had mentioned I should have a higher chance of getting pregnant this month due to chemical pregnancy. But what they never told me was if that was my period when I bled for 5 days. If anyone has any advice or anything to help me with this please comment. Thank you
