"i was first on implanon for 3 years until it was recalled and i had the nexplanon inserted in 2016.  i bled a lot with the implanon, at first the nexplanon was great, i never had a period.  now i am constantly spotting.  if i don&#039;t drink a lot of water, my body thinks i&#039;m dehydrated, and my blood will be red, but when i drink lots of water, its brown and clears up within a few hours.  i have had constant nausea where i thought i was pregnant.  it&#039;s also like i haven&#039;t eaten, and makes the nausea go away afterwards.  but comes back in a few hours.  it is very effective for birth control.  my husband and i, do not use condoms, so i know it is very effective! we are planning to get pregnant next year, and i cannot wait to get this out."
