@Daina my cycle is quite irregular but my app says I’m not due to start my period for 4 days.
I would wait to miss your scheduled period and try again. And then just keep testing probably once a week over a 2 week span, and if you still haven't gotten a positive or started your period, then maybe check in with your doctor!
With my first i tested 5 days late. I had 4 negatives and then tested at 10 days on digital and came back positive
How many days until you're supposed to get your period or how many days late are you?
