I am 25 years old and 64 days LMP. Ive taken over 10 HPT's all negative. I also took one at the drs office which was also negative. I've had symptoms of pregnancy such as headaches, lower back pain, frequent urination, nausea, sore breast, fatigue, exhausted, and bloating. My boyfriend and I have been trying for our second child for about 4 months now. Lately I've had random stomach cramps but nothing I couldn't handle. Any ideas what could be going on with me? I'm going to call my OB tomorrow to make an appointment.
