Am I really pregnant

Ka

Just took a clear blue pregnancy test and it came up with a fairly obvious blue cross to say pregnant!

A little back story, I had my implant removed after 3 years

on 20th February

I had my first period since it’s removal on 11th to the 14th March.

This app says my ovulation was 23rd March and my next period due on 7th

Could I really be pregnant?

Should I test again, if so how long should I wait??

Really hoping I’m actually pregnant but I know it’s early!
