Has anyone ever had a mix of positive and negative tests? Has anyone ever had a home PT not indicate pregnancy but later found out they were pregnant?

Backstory: I’ve never missed my period before except in April 2016 when I found out I was pregnant with our first and currently only child!

I am 10 days past due with inconsistent pregnancy tests and it has me concerned. I can’t get in for an appointment for 2 weeks.

Any advice would be greatly appreciated!
