Hi there, I have had an IUD for 8 months. Ive been bleeding every two weeks. But in the last two months I haven t, just a short three day period. But in the last few weeks i ve been having pregnancy symptoms . Im hungry all the time, extreamely tired, cramping, dizzy, ect. My period is due in two days, so I didn t want to do a test to early. But last night I found a squishy bump inside my vagina , is this a sign of pregnancy or just pms?
