I've had the organicup for about 6 months now, and holy shit I'm in love! It's truly amazing, it's like not even having a period. I rarely get cramps so I can easily go through the week without even noticing I'm on my period. I can sleep, go swimming, go to school, I can do whatever I want and I never have to think about my period. Never.
But! The first time I used it it were horrible. It hurt really bad and I got some serious cramps throughout the entire week, and I never get cramps. I decided to try again next month cause I'd heard you'll have to try it a couple times first. Since the second time I've been using it every month.
Don't give up, even if it's a struggle at first.
It's worth the fight!
