Hello, I am 30 and I have delayed periods for 40 days over the due date. So, technically, I have no periods since 70 days. In this duration, I have experienced slight spotting twice, (very dilute). I have appointment with OBGYN, but cannot get it earlier than two weeks from now. I took the tests four times, and they all turn to be negative. I thought it might be ovarian cysts or PCOS, but I am not sure about it. My friends suggested that many times, the home preg tests are not reliable. I am worried regarding this strange pattern of my menstruation cycle. With all the confusion, whether I am pregnant or not. Any related suggestions are welcome. Please help.
