Positive PT

Hi Mommies! I have a question, I am 2 weeks delayed based on flo app but I am irregular so I really don’t know how many days I am delayed. I took a PT yesterday and the 2 lines clearly show . I tried again this morning and still 2 lines. Any thoughts about it? Am I really pregnant or is there a possibility that I will get my monthly period any moment from now? Thank you in advance.
