I have always been irregular unless I was on the BC pill. For the last 2 months or so, I've been having spotting off and on--it's usually a bright pinkish-red color. Sometimes there is a clot, but it's always smaller than a marble. I've been having severe lower back pain, moodiness, etc. which should imply that I'll soon have a "normal" period. However, is it possible to get pregnant without having a normal period? It's been since January of 2007 that I've had a period. I took a pregnancy test in March that returned negative, but haven't taken one recently. I'm wondering if my body is attempting to have a menstrual cycle, and if I should just wait it out, or if these symptoms indicate something more severe. Help?!
