Nexplanon question

So January I had my first normal period with nexplanon.

Then February for the first time I missed my period completely on nexplanon. And had heavy clear discharge making me think I started my period but I would go to the bathroom and it was just discharge and it keep making me feel like I wet myself.

Then march I had light spotting only when I wiped 10-12 day after I had sex.

March 11 I got a new nexplanon because my old one was due out March 30.

Since I got the new nexplanon I have not had my period at all. So I figur it's just because of the new nexplanon. But I been having light spotting only when I wipe with the new nexplanon and I never had that with the first one.

So my question is, is it normal to have light spotting only when I wipe with the nexplanon?

Any other thoughts and opinions would be appreciated 😊

Thank you
