I started the ring and about a week later got intense itchiness and break through bleeding. It was supposed to be time for my period, and I thought since I timed it wrong possibly I was going to have it anyways. So I took the ring out. The itchiness went away immediately. Also, I could NEVER get the ring all the way in. It dropped down considerably, and I made many attempts to move it. Two days after I took the ring out I had HORRIBLE depression, thoughts of suicide and self harm. Also I was exhausted but unable to sleep. I feel a bit better, and I have no idea what it's half life is and if it will wear off, or if a new medication is needed to rebalanced the hormones. I hope not, as I had a bad experience with hormone balancing medications in the past.
