I'm late

So my period since ive been off my mirena has been of the first while i didnt have a period for two months then i had a period for 45 days straight .After the long period everything has gone back to a 22 to 23 day cycle and on my period for four to five days. I am now 6 days late past my period, ive taken two test both came out negative. Should I try again ? If so when? Or should I continue to wait to see if my period will start?
