I'm late

I haven't taken a test yet, and my period is always random according to glow I'm 4 days late and 17 days past ovulation.. I've been wanting a baby for 4 years and now when it comes time to take the test i find myself too nervous to do so.. for fear of another negative.. I know everything happens in God's time and that if it's meant to be it'll be but this will be my last child and I've never wanted anything so bad and I just don't want to be disappointed I've thought about waiting until March 1st but I'm also so ready to take one today.. Just venting a little and this is a safe place to do it..
