When to test?

Haley

So my peak was yesterday, and my husband and I have been BD, of course. My next expected period is the 27th, and I bought the First Response ovulation test kit with 7 tests and 1 pregnancy test. It's the one that supposedly detects pregnancy up to six days before your missed period. Should I test on the 21st or wait until closer to my expected period or after? I'm anxious, haha. Just planning ahead.
