Should i test again?

I had the nexplanon taken out almost a month ago(jan 7th). The week before i had it taken out i had streaks of red/pink/brownish blood in my CM. According to my calendar i am suppose to have had my period already. But my tracker says im 17 days late. A couple days before i was suppose to get my period i took pregnancy test but they came up negative (took them because smells have been making me nauseous, nauseated randomly, tender breast, high sex drive, and a whole bunch of CM, and super emotional). I took a test last Saturday and it was negative took one this morning because after eating breakfast i felt nauseous. Should i take more test? Im sorta freaking out because i didn't think it would happen so fast we just started trying so im nervous to get my hopes up .
