47 days and a week late... Advice please

In February I had a 49 day cycle lasting for 7 days. April 45 days cycle lasting 6 days. May 33 day cycle lasting 6 days. June 39 cycle lasting 5 days. My last period lasted 5 days and I am now on 47 days cycle still waiting for Af to come. Glow said Af was suppose to come on the sept 7th but I hit period late 2 times and now it says it should come on the 15th which would be 49 days...  I took 2 hpt and both negative.. If I go by what glow says Af suppose to be here on the 7th I am now a week late.. When should I take another test? is there any hope I could be pregnant or should I just count myself out this month...
