NEXPLANON before implantation had unprotected sex everyday?

There is reason for everything they tell you to do. Even doing a pregnancy test, you could still have been pregnant since they told you NOT to have unprotected sex 2 weeks before hand. The reason is a pregnancy test will not pick up on that early of a pregnancy. You could have been pregnant even though the test came up negative. You did nothing a you were supposed to and NOW you are worried? Come on! It sounds to me like you are really just hoping you will get pregnant. Yes, you could very well be pregnant or it is possible that it is side effects of the Nexplanon. The only thing you can do is to test. I'd wait until about Feb 12 or so then test.

Now is not the time you should worry about pregnancy, that comes before you have unprotected sex. Its time for you to start respecting yourself and demanding that you aren't used like that. If he wanted to have unprotected sex, you should have said no. If he doesn't respect you enough to listen to you, you need to find someone who does. Its your body, you determine how its treated. Whether or not the implant works for you, it would not have been working until you'd had it for 5 days.
