I noticed my absent period in April meaning my last period was in March and I've still not had a period and I have an expired iud mirena, expired over a year ago and I have 6 year old twins that while I was pregnant with them it was undetected until 6 months along. I have evety symptom of being pregnant including fetal movement except the movements change as if sometimes I'm not as far along than sometimes like I'm farther along. And I've tested negative blood and urine tests. And am not showing as if the baby or babies are being carried in my back, including visual movement in the dront while feeling movement in my back.
