Hi there, Ive had my implanon for just under two years. Ive still had regular periods up until now. The current one is 9 days late. Im extremely nauseous, im dizzy, tired, moody, my boobs have grown in size and my tummy looks like a balloon. Ive taken a home pregnancy test but its negative. Is it possible to be pregnant still? Could the negative be false? Ive got a lot of pressure on my uterus and im really concerned its failed. Thanks in advance,
