Feeling discouraged

I've posted about this before but I'm still discouraged. I got a very very faint positive 10dpo and have BFN since then (currently 14dpo) I was told it could maybe have been a chemical pregnancy but I'm the type of person that does a lot of research and everything I've read says it wouldn't happen that early.. AF due tomorrow and I'm praying she doesn't show her ugly face 😔 should I just give up hope and expect to just try again ?
