Could I be pregnant?

Hi, wondering if I should’ve concerned or not I got nexplanon 3 months ago, I bleed the entire two months and my period stopped about a week ago I’m supposed to start it again in 5 days. My boobs are very sore and nipples like very bad. My boobs also have stretch marks that showed up in the last week. Me and my boyfriends usually wear condoms not every time but he does withdrawal every time. Is there a possibility that I could be pregnant? I have no idea if this matters but currently I have a virus and have had a fever.

* my period is late my 2 days and I took a test the night and morning of my missed period and it said not pregnant could I be or just nexplanon side affect
