Endometriosis
"So I&#039;ve had the Implanon NXT in for a few days now.  I have a huge bruise where it was inserted and having a lot of headaches. Really hoping the headaches will pass. I have already noticed my period slowing down massively and my skin clearing up heaps so definitely a plus with this device. It was recommended to me because my periods are generally very heavy and I have become iron deficient. So as I said, hoping the side effects will pass."
