Worth one more test?

Hey guys would love some opinions. As you can see my cycles have been varied since my last miscarriage,but they kind of settled between 29-30 last few months. My question is I haven't had a period since 20th sept and I'm now on day 40 on cycle, done a test on the 22nd October was negative, should I take another test, or just filling myself with false hope. Any one had similar experience?
