FOR THE LADIES! Those of you who have menstrual cycles.FOR THE LADIES! Those of you who have menstrual cycles. When you first started IP, how did it affect you? I ask this because I have the nexplanon in and it was new back in August. I have not had a cycle since November and then day 2 of IP I started and it lasted until the following Sunday (last week) now here we are on my 2nd day of starting my 3rd week and I've started bleeding again! It's so annoying. How long until my hormones regulate out? I really hope I don't bleed for 8 days this time.
