What can I do?

Hey ya’ll, so in the past I have a history of wildly irregular in timing but normal in symptom periods. Like my periods can ranges from 26-48 days apart but all the symptoms are normal and indicate a period writhing 4 days.

This month I’m 44 days, but my symptoms are just slightly off and far longer lasting. I’ve had the period- warning symptoms for a week and a half but every pregnancy tests I’ve taken is a very clear negative. I say my warning symptoms are off only because I seem to be slightly hungrier than usual. I’m not sure if it’s the holiday season or if there really is a baby hiding and not showing up on tests, but I can’t afford to go to a doctor till insurance kicks in mid January. Any advise?
