2 weeks past my last period. Mirena fell out a month ago. This was the 2nd normal on time period in 7 years. I have been having slight lower abdominal cramping and nausea for about 4 days. I now feel pressure near my uterus, and mild back hip pain. I do not think I am pregnant but it is too soon to take a test. Also fee extremely moody and bloated, gassy..
