nexplanon- is this normal or should i go bother the doc?

Hi all, wonder if anyone has experience of this? Don't like bothering the doctors for no good reason, but it's worrying me a bit now.

I had the implant put in after my second was born, 18 months ago. No problems with it at all, zero bleeding. Until now. Had on and off bleeding for the last three weeks, one episode was like my usual period, other two just light spotting for 2-3 days, but I have never had this before, not on Nexplanon, or any other contraception i've been on, or off. I know Nexplanon can cause bleeding that gradually gets better, but this is the opposite?

I did breastfeed until 8 months ago- don't know if it's relevant.

Would you worry or wait and see?
