I just want to dance at the wedding in 3 weeks, and not worry about it in Spain. Getting official results today but if it's a cyst they'll tell me to wait and see. I just want to have sex, enjoy the wedding and honeymoon. I've never had one (that I know of), why now?

Any advice on how to make it go away fast? Over a week and a half, I'm already on birth control (implant).
From the little I know about reading ultrasounds it looks like a large cyst, maybe 5 cm(?) Regardless I'm in pain, sad, and frustrated so I'm just venting.
