I have two beautiful, healthy girls, 7 and 3, and have been trying to conceive for about 6 months. Im 28 years old now, and have had no problems at all conceiving the other two. I have periods just about every two weeks, and have no clue why. But, I have not had one in a month and four days with no pregnancy symptoms and negative tests what should I do? Please help, I am desperate.View Thread
