Could i be pregnant ?

Ok so i had unprotected sex on friday (jan 4th) and he finished in me. my period was suppose to come on that sunday (jan 6th) we had sex again on tuesday (jan 8th) and he finished in me again. Now my period is 5 days late. I am on the implant and this has never happened to me before. i got the implant about 6 months ago on July 31st. friday was the first time he’s ever nutted in me. I’ve been having a few symptoms: milky discharge, strong sense of smell, fatigue, a few cramps, and my appetite is all over the place ( i dont be knowing if i am hungry or full ) . and i normally have clear skin on my face and now im seeing a few bumps
