Sister in law texted me

Maria

She has been on nexplanon for over a year so she doesn't have periods anymore. Well she started spotting last week. Last night she sent me the digital one. Then this morning she sent me the middle one before the 3 minutes were up. Then finally after the 3 minutes she sent me the top one. Evap line or could she be pregnant even if she's on nexplanon birth control. Thoughts?
