So I have nexplanon implanted in my arm... when my doctor implanted nexplanon, she said not to have unprotected sex until a week after and I had unprotected sex the same day it was going to be a week... its been 5 1/months after and I never had a period but I am spotting... my periods have always been really heavy so for me to be spotting is very strange, is it because of the birth control? Also, I sometimes feel like if my baby was still in my stomach kicking... is that normal??? I also eat the same amount as I did when I was pregnant and it's causing me to gain a lot if weight...
