I am 28 y.o. and have had an abnormal period since they have begun. I have 2 children delivered by c-section and had my tubes clamped 2 1/2 years ago. I have not had a period since January which lastest 3 weeks. Now my breast are tender and I am having sharp pains near my lower abdomin and my GYN says there is nothing wrong and offers birth control pills as a solution what should I do?
