Missed period by 22 days 😱🤯

Miranda

I haven’t had my period since April and I still get a negative test even blood tests. I have no idea what’s going on normally I am super normal on my period my cycle lasts 26 at max 28 day and now I’m on my cycle for 50 days 😭 should I worry or am I just driving myself crazy ? I have seen a doctor but they keep telling me to wait till I’m 8-10 weeks late before I can get any other tests
