pregnancy after copper IUD or crazy?

Been awhile since I went through this (youngest is almost 8) got the paragard after having him. Last month it fell out first day of my period. For at least the last four months my cycle is 32 days like clockwork. Today is day 33, no spotting or cramping. Tender breasts (which I got while pregnant but also now before AF) clear cerivcal discharge, cervix is still high, and my uterus feels so heavy. Bending over or even sitting is sort of uncomfortable and feels like pressure. What gives? I've never had normal look with pregnancy tests I get a feeling, and then I get a negative test until weeks after a missed period.
