Posting for traffic because I'm terrified!
I've had the implant in since summer 2018, so it's overdue to be changed by 6 months thanks to the pandemic they forgot to make an appointment for me and I forgot to chase it up.
Have an appointment to have it changed next month but the nurse has advised I take a pregnancy test just to be sure but says it should still work up to 4 years, even though they say 3 years?
I've not had any symptoms, I don't have periods on the implant anyway the only thing I have had is bad heart burn and sickness but I have a condition that causes that anyway... what's the chances I'm pregnant? Can't get a test till tomorrow! 
I'm terrified as I can't get pregnant again I had 3 stillborns just before the implant and made a promise to myself I'd never put myself or my children through that again.
