Chemical Pregnancy?

Ja

I recently had my first period since having my son on his first birthday(June27). The next month I realized I should have had my period already. After a week of nothing I took a test and it was a super faint positive.

The next day I tested again and I could have sworn I saw something even fainter. The next day, negative and then finally after being 2 weeks late I get my period... could this have been a chemical pregnancy?
