Late period

My period is usually on time. I’m 5 days late, almost 6. That’s unusual for me, but I’ve also been very stressed this past week with work. My boyfriend and I had sex less than a week ago and he pulled out (but isn’t it too early for me to be pregnant from that ?) also , we have sex maybe once a week. Always condom, except in the beginning we’re raw for just a minute or two.

Is it too early for me to test ? Should I wait ?
