Nexplanon almost to the end mark..

xx

Quick question for anyone who had this experience or similar, I get regular monthly periods with Nexplanon had no issues with it whatsoever. Inserted in 2020. Gets taken out 2023. But the issue is lately for almost 2 weeks now I been nauseous pretty bad ! I’m not sick, I puke sometimes ( not like me ) my period is due tomorrow according to my apps but do you all think I’m losing effectiveness of my implant that’s causing this nausea?? Could it be a chemical pregnancy? I’m just a little lost TIA
