My menstrual cycle is currently at 37 days, I normally am on average 27 days and if I am irregular my cycle is often shorter than the average 27 days. I have done a HPT this morning and it was negative. This is the first month my husband and I are trying to conceive. On the 31st day of my cycle, there was slight bit of blood in my urine but not enough to leave any spotting marks. My tempreture for the last seven days (first thing in the morning before getting out of bed) has been 37.7 or 37.8 degrees celcius. I can't help but feel different - sore lower back, tired, moody. Do you think I could still be pregnant or should I accept that I am not? thank you.
