Late period according to glow, normal??

So my period is usually on time. At most it's 2 days late. My bf and I have been having a lot of sex recently (just moved in together) but we've used a condom everytime. Make sure to put one on before intercourse ever starts. I'm also on the mini pill. According to glow I am currently 4 days late. Should I wait for a week or should I go ahead and take a test? Is this normal for glow or is it pretty accurate? I'm also new to the app. Help please!!!
