Started Nexplannon as a beginner

(21,F) As the title states, I started nexplannon 2 weeks ago, tomorrow (the 29th of may).I didnt have my period before i got it put in and i havent had it yet. But ive had major cramps,gained appetite and mood swings. It feels like im on my period but no bleeding is involved.

I have been on birth control before, i took the pills and did the depo shot. But they both made me very depressed.

I just wanna know if all this is considered normal since i literally just started the implant. All advice and tips would be appreciated. ☺️🥲
