Im 4 days late

So i ovulated on the 22nd according to the app. I had sex on the 21st AND 22nd & not im 4 days late. I’ve been super emotional & been having weird discharge. After i ovulated i kept having clear discharge for about a week. After that i started having headaches. Today i also had cramps. I thought i was going to get my period but nothing besides clear & white discharge. I tested 3 days before period was supposed to get here & nothing. Do you think I could get a positive already or should I wait more time?
