hey. my period cycle is 30, 31 days. It's regular, rarely irregular. I had it 5 days early. It pretty much lasted for 3 days even though I had spotting afterward. After the bleeding stopped, I got really bloated... beyond how I normally do. I have been experiencing nausea, loss of appetite, a dull constant cramping in my lower abdomen (varies from left to right side), aching in my lower back, stiff neck, and what feels like pressure or cramping near the rectum/vagina. Am I just ovulating? Or do I have an intestine blockage or something?
