irregular periods

Heven
What are some things, remedies or recommendations you have or have received by your care giver for getting periods regulated?? I tried to get an appointment today but they don't have anything until Jan. 23rd 🙄 I'm almost on day 50 of my cycle...we did just make a big PCS move with lots of stress so I'm assuming that is my problem but I never have regular cycles to begin with (but never last this long) 
I have period like symptoms but no period!! I took one test a few days after missed period that was a BFN. anything helps!!
