Hello ma'am and welcome.
From the given history, there seems to be a history of mild irregulariry in your menstrual cycle and although pregnancy
could be one of the causes for your delay this month, it is most certainly not the only possible cause.
I would recommend a repeat home pregnancy test, but this time using an early morning urine sample. If the same continues then you may have to visit a doctor to confirm/rule out pregnancy and also look into other possible causes.
Hope this helps.
Best of luck.
