After a year of irregular bleeding and spotting with the Implanon implant, I had sex without a condom and my bleeding stopped. Could I be pregnant? #105/15

Q:        I’ve always been extremely paranoid about becoming pregnant, which is why I got the Implanon implant in the first place, but my irregular bleeding is worrying me. I got my implant in September 2013, and have had irregular bleeding ever since that usually ranges between a constant light to heavy bleed. Also a light to heavy flow of brown/black discharge (this never bothered me).

I had sex without a condom a couple weeks ago, and around that time my bleeding stopped and I started a VERY light flow of brown discharge with some blood, so light it doesn’t really show up in my underwear unless I try to force it out. I’m worried that the timing could mean pregnancy.

Now I know I’m probably being paranoid because I’ve heard good things about Implanon’s effectiveness, but I also stupidly searched online and read some of the horror stories of women becoming pregnant while on Implanon.

Is your Implanon still in place now?You certainly have been patient with the bleeding/brown discharge over a very long period of time.While no method of birth control is 100% Implanon and Nexplanon come the closest of any of the contraceptives.Can I assume that you were NOT pregnant?

Tell me what your pattern of bleeding is right now.  Tell me what you want me to know about you and your implant today.

I assume that you were not pregnant at the time you sent in your question.
