Should I test or is this just my bc?

Me

Hey y’all I recently got nexplanon last Thursday which was a day before my next expected period. I figured my next one would be late due to me starting a new job and potentially synching up with my new coworkers. It’s been almost a week and I still haven’t gotten my period. The most I’ve had is a bit of brown discharge that lasted about 2 days. It really wasn’t enough for me to put a pad or anything on. I have also noticed a lot of wetness down there to the point where it makes me think I’ve gotten my period but when I go to look it’s clear and watery. I did have some cramping and felt like my period was coming the day before I got the implant, the day of, and the day after but as I mentioned flo has not made an appearance. Every other time I’ve used bc and started it a few days before my next period I still got it on time or a day late. I’ve never been almost a week late for a period
