haven't had a period since May 13 I have always had regular periods and have never been late. I have had all of the symptoms- morning sickness, nausea, food cravings, peeing more often, backache, headaches, moodiness, etc. I have taken 3 pregnancy tests and all came back negative but still feel pregnant. I was wondering is it normal for the preg. tests to come back negative if i am pregnant and next week i am going to see my gynocologist to get blood work done. Do you think the blood work will show that i am, if indeed i am, although the urine home tests all say negative?
