Can’t stop thinking about this ...

So I had back to back babies one in aug 2016 & one in nov 2017.

After my 2nd I got nexplanon implanted in my arm

It’s feb now , I haven’t gotten my period ( I breastfeed and formula feed )

I e been having abdominal pain ( like bad bad cramps ) sometimes it’s mild sometimes very painful. Also been experiencing nausea, weakness and my stomach always feels like it’s dropping/thumping.

I googled and I read that this can be a sign of ectopic pregnancy.

I don’t have any bleeding though.

Could this be ectopic pregnancy? Can that even happen with nexplanon?

I have a docs appointment on Tuesday but I can’t stop thinking what’s wrong ...
