Nexplanon Birth control implant

Anizjah
Hi I just got the implant put in Friday the 13th & I wanted to know how careful to I need to be while it's healing ? I'm nervous about it. I just had a headache earlier since I've gotten it .. not too bad bc it's so effective & I have 2 kids already so I'm willing to deal with the cons if they're not too bad.. but if anyone can tell me anything about their experience after getting the implant please let me know
