So my period is 41 days late. My periods are normally right on time because I have a Marena IUD and my cycle is average 26 days long. Every pregnancy test I take is negative but I feel pregnant. I've been nauseous, headache, slight cramping , feeling bloated, tired, I spotted one day about a month ago just real quick then it stopped and my gums have been bleeding when I brush my teeth with a soft bristle brush when they never did that before. I seen my Dr and she did a vaginal exam and said my strings are still in place and did a urine pregnancy test that was also negative. She then sent me for a interuterin ultrasound about a week ago to check placement of my IUD better and still haven't heard anything from the Dr about it. I don't know if I'm pregnant or just if it's all in my head.
