Hello there I truly feel your pain. After I gave birth to my daughter in 2008 I started to have alot of new pain and bleeding. Was diagnosed with endometriosis. The bleeding was severe and drained me of energy. I was put on numerous contraceptive pills, implant, coil nothing seemed to work. 8 years later I literally had to beg for a hysterectomy. They dont like doing it if your too young. But in 2016 I finally had the surgery and yes for me it did stop the day to day bleeding. After I did enter into a relationship but sadly still had pain during and after sex. It took me a long time to come to terms with the fact that I could not have full sex it was just to painful, and caused so much pain days after. I'm OK with maybe foreplay you know and I'm lucky enough to find a man that is OK with not having full sex. (Toys are fun) I dont want you to give up. There is light at the end of the tunnel if you can make important decisions (possible hysterectomy) and be comfortable in your own skin and say to yourself 'this is my normal' life can go on with a few tweets.
Talk about your feelings too dont bottle it all up. I do hope you find peace xxx
