Okay, my girlfriend and I are trying for a baby. For about 3 months now. She last had a period 39 days ago. We took a test around the 31 day mark but it was negative. We are taking another test on wednesday. She's had cramps for around 3 weeks now, been drowsy at times, had really bad headaches in the last few days, as well as apparently having an unusual craving for the smell of petrol. I just wondered what the chance she's pregnant could be this time around, given that she's so late, but taking into account the negative we got on 31 days. And, also, if we get a negative, I will be quite worried about the lateness and if there could be something wrong. Obviously going to the doctors for a pregnancy test is the next logical step if we get a negative, but I also wondered, how long without a period (when not pregnant) is considered unhealthy?
