I have just begun taking ortho tri cyclen lo oral contraceptive and have noticed a tingling in my left arm and hand. I've also had pretty severe anxiety and difficulty sleeping. Are these side effects normal? The mood swings have gotten so bad I've decided to stop taking it and am waiting for my doctor to call me back. I'm 18 and in good health. I've only been taking this for close to 3 weeks. What should I do?
