I am 25 years old. I have had two children back to back. My youngest just turned 2. I have had an IUD since she was a couple of months old. Very rarly do I have a period with the IUD. I woke up feeling terrible this morning. I haven't felt good lately(thinking maybe it is something going around)I have felt sick to my stomach all day. Hurting, like period cramps. The last time I used the bathroom a glob of this jelly like substance fell out--kinda like a mucus plug. I still am hurting and feeling sick. Could I have been pregnant, but aborted it because of the IUD? Could I still be pregnant? Or could it be that I just haven't had a real period in so long I've forgotten what it feels like? PLeaSE helP!
