I got nexplanon on a Tuesday and I was planning to have sex with my boyfriend on Monday night do you think it's absolutely necessary to wait the full 7 days or is it just for precaution? I have heard of girls asking after having sex 2 and 5 days after they received nexplanon but never really got an answer and never found out if they ended up getting pregnant or not. I did not do it during of right after my cycle I feel it should work after 6 days but I just wanted to see if others have done it and can tell me
