So I got my IUD almost two weeks ago. I've been feeling my strings and after a few days of getting it the strings shrank up just like my gyno told me they would. But I just felt my strings again and they were way closer than they were a week ago! I felt all the way up to my cervix and I didn't feel the bottom of the IUD. It just seemed sort of swollen but I don't really know. Is this supposed to happen or is something wrong?
