Answer pleaseeee :(

Honey don't worry. The implant is foreign to your body. It is just reacting to the added hormones. I went through this with my own implant about 4 months ago. It goes down in about 2 weeks

If you're feeling fatigued, nauseous, tender breasts, an more things this are early sings of pregnancy. If you did use a condom( and it didn't break or anything) when having sex you should be fine. It's probably the shot 

I had a few symptoms with my rod. They should have done a pregnancy test before putting it in. If you're nervous take a test for the peace of mind. 

if you've had two periods it's unlikely unless you conceived since your LMP. If your worries take a pregnancy test. It sounds like your experiencing side effects from your birth control though. 

If you have had two periods then your not pregnant. But take a test and you will know for sure.
