When can I take a pregnancy test

Heather

Okay ladies so my first day of period was July9, 3 days. I believe I ovulate early about July 21. When can I take a test and if pregnant would be positive, I’m away but I brought one first response line test and a cheap one from amazon, I’m hoping this is my month but don’t want to wait, opinions please

Thank you and baby dust to all ❤️🖤💜💙
