Late period

Madison

Hii. Im currently ttc for baby #1. I've never had a positive test and we've been trying for almost 4 years. Im currently 11 days late and the only thing is im tired. I've never had this symptom before and im really nervous to test. I have a obgyn apt on 12/15 for a check up. Should I wait and test then or test now. I've felt just off like not myself but no sickness. I did have some weird mild cramps yesterday but they were more on the side and not where they typically are if AF is coming. Any advice? Thanks!
