Should I have it removed ?

I got nexplanon after my 2nd baby , it’s been almost 10 weeks and I been going thru a lot of symptoms. Some days I have a sore throat / flu like symptoms. I have crazy headaches that don’t go away, no my even with Tylenol.

I feel weakness/tiredness. I feel nausea. I have bad cramps ( haven’t gotten my period ) and most of all I’m gaining weight everyday because I feel hungry and I crave sweet things all the time .
