Hi, I am a mother of 4 boys and I am trying to have a girl. My LMP was on January 18, 2007 had all symptoms, except the test results were negative, 8 HPT's and 1 blood test, all negative and still no cycle. Could I be pregnant? I feel pregnant, and my OB/GYN said I could just have low hormone but to wait 2 weeks and then he'll do an exam. Is it possible to be pregnant and have it not show up on tests this long? With my other pregnancies they all turned + immediately, hope there still is a chance I could be pregnant. Also, I had my right ovary removed in August 2005 due to a large ovarian cyst, and we had to wait 3 months until we tried again and the month we tried I conceived and had a baby boy in July of 2006. But would that cause an irregular period? If I only have one ovary?
