"had implant fitted 13th december 2014. had one period in december and then nothing for two months. february i started bleeding again and have been constantly bleeding since (it is now march 2016). it occasionally stops for 3-4 days and when i say occasionally i mean maybe one every 5 months or so... tried cerazette at the same time and it didn&#039;t stop. took norethisterone for a week when i went away, three days after stopping i started bleeding again and i have never felt anything like it. i was off work for two days, couldn&#039;t stand up with the pain and was bleeding through tampons in less than 2 hours. along with the constant bleeding, i have terrible mood swings and extremely low libido."
