I always get my period the beginning of last week of the month, it is now mid december and i still haven't gotten it. i took a test on 12/8, 12/10, 12/13, and 12/15 and they were all negative. i am using paragard for birth control and that's it. i had my daughter a year ago(-3days).i have a ton of signs that i may be pregnant, my head hurts, lower back hurts, lower abdominal cramps, dizziness, nausea, heartburn, fatigue, peeing all the time, extremely moody(went off on my fiance for 20 minutes because he bought regular huggies instead of the Santa ones), bloating, milky discharge, and heightened sense of smell(i could smell a pack of gum that someone had in there pocket at work). On top of that when i was pregnant before i would get these shooting pains that would start in really lower back almost to the butt that would shoot down my legs, well those started today. Don't know what to do, very confused.
