Feeling confused

Jessica • SAHM aspiring physical therapist
So my last period was from April 18th til the 23rd. It also started later from the previous period calculations. This would be day 6 of no period, took a test the first day of missed period and got a negative. Took one the third day, got a negative :/ having light lower abdominal /in the hip area type cramping with zero spotting. I logged my last period as a 36 day count since it was late! Help!!! :(
