Pregnant on nexplanon?

Hi ladies, so I didn’t think I would be back on this app so soon but here I am and I might be pregnant again, nervous and shocked because of the reasoning that I’m on nexplanon like how right? I dontknow for certain but there’s a faint line on the left, some may see it some may not but it is definitely a faint line on my end, I am a mother of 3 my first passed at 2, and my second and third are 2 1/2 and 11 months, so I wasnt expecting this at the least, can anyone see the line other then me could this be wrong? I’m taking another tomorrow and after that I’m calling my dr. There’s been plenty of horror stories about getting pregnant on this particular birth control so I’m more scared then anything to be pregnant again but if I am I’ll take is as a blessing and pray for the best, I appreciate everyone’s feedback, thank you in advance!
