Nexplanon and pulling out

Stacy • 19, College Student, Sociology major

I know I’m going to roasted for this but i got my Nexplanon implant nov 12, I had unprotected sex nov 13th into the 14th(around midnight). I was not on my period. He pulled out just in time. I’ve been on this birth control before but I took it out for mental health issues. I’m alittle worried but not really. Would I be able to take plan b on top of the bc? Do I even need to? I know it’s 99.9% effective. Should I stress about it?

Update:

I took the option two emergency contraceptive within the three days from the unprotected sex. I have a stomach ache and I feel like I need to take a 💩 but I haven’t. My stomach is definitely upset though.
