Abit fed up!! CD 51!!!

Ruby
So I'm CD 51 today. No AF no BFP! Hate being in limbo. Just want something to happen already. Either to get AF so we can try again next month or BFP. I moved abroad 3months ago since then my AF has been so outta wack. Iv had a CD of 52 then 18 and now I'm on 51 again. Anyone experience anything similiar. Normally I'm like clock work and my CD is 30days. Don't know what to do? ?
