I had Nexplanon inserted on 7/25 (2 1/2 weeks ago?)…

 ….We just started having sex again a week ago. I haven’t used a condom with my boyfriend since… I’m supposed to get my period today. What should I expect?

It is important to know that once someone has had the Nexplanon for a full week, they are 99% protected from pregnancy even if ejaculation in the vagina occurs.

The Nexplanon, however, does not protect against STIs. Only condoms and/or dental dams can do this.

In terms of your period, a very common side effect of the Nexplanon can be irregular bleeding. Some people lose their period completely; some have irregular spotting, and some people bleed more for the adjustment period. Sometimes it can take anywhere from 3-6 months for the body to adjust to the new hormone, or some people have unpredictable bleeding for entire time.  The reason this happens is because Nexplanon contains the hormone Progesterone, which over time stops the uterine lining from building up. Sometimes it will still build up and then shed. This is why someone may not have a period, or may have irregular bleeding. So since every body is different, we cant quite predict what your bleeding pattern will be. Just know that this change in period is completely healthy and okay.
