Im currently 18 days late. Last period was December 18th. Multiple tests all negative, blood test was at a 2 and my ultrasound came back normal so nothing is wrong and I'm not pregnant either. I have the IUD but I'm getting it out cause my hubby and I are gunna ttc our 3rd and final baby. The copper iud is not known for missing periods, I've been on it 9 years this year and haven't ever missed a month. So, on that note has anybody else ever missed a month just because?
