So confused 😐

China

Two days ago I had heavy egg white in my underwear felt like a period was comin but it didn’t now two days after I’m spotting which according to this app it’s ovulation but as you can see my last period were two and half weeks apart which never happened but they weren’t as heavy and no clots… I’m confused I want to test but I fear negatives. Been off nexplanon for 1 yr and half
