Speaking from my own experience, I had implanon removed on 11th of January this year and am still not pregnant. My periods returned after about 6 weeks and I?ve had cycles varying in length from 28-36 days. Things have been getting progressively more ?normal? and I think that my periods are getting heavier ? from less than 48 hours to over 3 days now with a good flow. I hopeful that this month might be good for me!
