confused...

I have an irregular cycle (comes from playing sports and excersising my whole life). Recently I've been feeling weird, bloated, nauseous, super tired, and definitely craving certain things. I have the nexplanon bar implant as birth control which I've read can stop working before the three years is up. I'm spotting today and not sure what is going on. On top of that I've had reacurring dreams of finding out in pregnant. Should I take a test or just wait till my doctor appointment on the 9th?
