Nipple pain with implant

I got my first nexplanon bar inserted in December and have had a few symptoms of that such as mood swings and irregularities in periods, over the past few days my nipples have started to be tender and today they’ve felt like they’re on fire. One of my friends said it’s likely to be from the nexplanon as it tricks your body into thinking it’s pregnant. Has anyone else experienced this? Is there any way to relieve the burning feeling!?
