Conceived after a chemical pregnancy

Hi! Have anyone ever conceived after a chemical pregnancy?

We ttc right after the chemical pregnancy ended. Didn’t use any opk we just waited three days after it end and start the deeds on cd 5. Started the deeds every other days for two weeks. AF was supposed to start on Nov. 11, 2020. Now I am 8 days late and took a home pregnancy test ended up with a BFN😭. Definitely do feel very tired, bloating and sore breast. I’m just confused with this cycle since af is late and the ht throws me off. Praying that we conceived. Does anyone ever encounter this kind of situation?
