UPDATE TTC. NO PERIOD NEGATIVE TESTS

Mallorie
Okay so I'm TTC for about 6 weeks now. I originally was on the nuvaring. I took it out the end of December and started my period from Jan. 3rd - 6th. My app said I was supposed to start the 27th and I still havent. I changed my cycle days from 26 to 28 and it then changed my start day to the 31st, still haven't started... I've been cramping SO MUCH. I've taken multiple tests and they're all negative??? Not even a faint line? Have I not started because of my Nuvaring and my body's adjusting or am I pregnant???? I'm so confused and very impatient. Lol any advice ladies??
UPDATE: I still haven't started ladies and I'm still getting negative. Please give me any insight.
