Negative Screens + Implant + No period = Confusion?

I’m pretty confused.. alright so I have the Nexaplanon Implant which will be expiring next month on 3/7. My last period was 12/19-12/24 and I haven’t gotten my period since then. But since my implant is about to expire, I’ve been pretty regular. I’ve taken four pregnancy tests and they all say negative but I still haven’t received it yet.

The kicker? I won’t have insurance to go to a OGBYN until April. 😭

Could I be pregnant?
