Im not sure what to do here

Im hoping I wont get too much hate for this because I'm 18 and extremely responsible and mature in every way I can be, until now. I got the nexplanon implant on April 30th, but I had unprotected sex two days prior, the pull out method was used successfully and we use condoms 99% of the time. The clinician told me that the implant could make my next period late but its been 6 days since it was supposed to start and I dont know if Im just being paranoid but Ive been noticing some of the early pregnancy symptoms, just very mildly. I can and will be taking a pregnancy test soon but I still live with my parents so I need to hide it from them until I know anything for sure. Im just scared because I dont know if I could handle an abortion or if we could handle a baby. My question is, based off of this, could I be pregnant?
