Ive been on my period for 2 weeks going on 3 its been so heavy that ive had to change my tampon and pad (because ive been wearing both) every hour tonight in a matter of 3 hours I woke up twice soaked in blood. In February of 2017 I got the Nexplon removed from my arm in August of 2017 my periods started back normal flow and last only 7 days witch was my normal cycle and happened every month on the dot. Ive had cramps that are so bad they take my breath away sometimes and bad back pain.
