I had my Mirena removed the 20th of January. after having it 9 months. On the 21st I started what I assumed was a period and it lasted 4-5 days. I figured AF shoCanuld start around Feb 18th. I had all the pms symptoms and was sure I would start 'tomorrow' but all I got was very, very, VERY light spotting. So light that I didn't even have to wear a pad. I've taken 3 hpt and all have been negative. Can somebody please tell me if this in normal?
