Can I be pregnant or just im the implant ?

Alejandra • 12’08’17👼🏻💖
I got the implant inserted on January 26.. I got asked if I had unprotected sex the last past 2 weeks I said no because I was scared they would judge me... But I really did.. My period is 10 days late today.. Is it possible im pregnant or just the implant side affects?? 
Sn- I am not able to take a pregnancy test because my mom doesn't know about all this and I don't have any money rn I am not working and I can't ask my older sister because she will end up telling my mom. 
Help?
