I have the nexplanon arm implant, have had it since last August. Well me and my other half don't use protection and he doesn't pull out, we just kinda rely on my birth control. Well my period is 6 days late according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>, and I feel nauseous every morning and night, I'm also very tired more often. I took a test last week sometime and it was negative mind you it was before my period was supposed to start, should I take another?
