My last period started April 29th so my next one should be due today but I started spotting 5 days ago really light and brown. My periods are always right on time and really heavy and dark blood. I'm also super moody today, I was crying all morning and got mad at my husband for not wanting to go with me for my cars oil change. I rarely ever get emotional and my husband and I never fight, so it's really weird. I've also been freezing the last couple of days, and it's been 70 out.
