endometriosis
"Having endometriosis Nexplanon  is really useful for me, especially with only being 24 I don't really want to face going in for lapraocopic surgeries as it'll leave more damage in the long run.  I get the side effects of; prolonged bleeds (theyre not periods as my gynaecologist informed me), slight back pain, weight loss. 
So far my mental health improved and I feel mentally better than before having it in, and acne whilst still existing has dramatically reduced.

Hopefully it should stop the rest of the cysts and endometrium from building up on my ovaries!!!"
