What do you think?

I have the naxplenon implant and 3 weeks ago I had sex with my boyfriend on a Saturday and the week after that on wendsay I started feeling nauseous my period stopped and then on Monday I started spotting and vomiting and my breasts started to hurt wendsay I stopped spotting so I took a pregnancy test and it said positive so then I went to go double check with a local gyn and they haven't gotten back to me so now I'm stuck thinking if I'm pregnant or not my period hasn't come back nor the spotting and I'm seeing the same symptoms of pregnancy. What should I do? Am I actually pregnant or is the nexplanon playing with me again?
