When I had my Nexplanon put in about 10 months ago and have started to have pink discharge something I've never had before. When me and my boyfriend had sex without using a condom for the first time a few weeks later i had pick discharge and had spotting now 3 months later I'm having it again but am having heart palpitations suddenly, sore breast, headache,fatigue, and nausea is this normal I have been feeling this for 2 months now I missed my period last month on July and now august having the pick discharge and am feeling weird more than I usually do does anybody have a answer to this I'm concerned?
