Help finding my due date?

Erin • Mama to 3 beautiful girls
I have an appointment on January 29th. I'll have an ultrasound done then too, but I'm just curious if anyone has a good guess as to when my due date will be. 
 I got the Mirena taken out on November 9th and I got my period for 7 days starting on the 10th of November. I had very light spotting two weeks later for less than a day. 
I never got my period in December. I took a test a few days before Christmas and it came back negative. 
I took another test on New Year's <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and 2 very dark, undeniable lines showed up. I took two more tests that day and both showed "pregnant" 
This is my second pregnancy. 
I'm just anxious to find out when we get to meet our little angel :)
