Good morning sis! Yan ay common side effects talaga ng implant, lalo na sa first few months pa lang, kaya don't worry sobra, a few of us moms sa group namin experienced na yan after getting it inserted. The nausea, dizziness, at headaches usually settle down after 3-6 months as your body adjusts sa hormones, but if it's really bothersome or hindi humihinto, definitely check with your OB kasi baka kailangan i-adjust or may ibang option na mas comfortable for you.
