Hi! My husband and I have been NTNP for about four months now. Currently I am three days late which is unusual. We use no form of birth control. Since the day before AF was supposed to arrive I have been feeling on/off pressure in my lower back and on/off very mild cramping. I have also been experiencing headaches, difficulty sleeping, increased discharge, I have been far more emotional - getting upset at the most ridiculous things, I've also been feeling bloated (some of shirts have been feeling tighter but I haven't gained any weight - I've checked) and my breasts have been very sensitive and occasionally feeling heavy and tender. So based on all my ramblings, could it be possible that we have a baby on the way?
