So confused!

Ami • Follower of Christ, married and pregnant with 4th baby!
I had my mirena removed May 23rd.
​That night my libido went way up! I am pretty sure I was ovulating. I had what seemed like ovulation pains the day before and day of the removal. My CM was a lot. 
​The next day my DH and I had unprotected sex. Then 2 days later we did it twice that day. 
​a few days later I bled very lightly for 2 days and the 3rd day it was barely anything.
​Yesterday morning I had an awful sharp yet dull pain for a few minutes. A few hours later I went to the restroom and after urniating I had a little pinkish tinge of blood. That was it.?
​This morning I checked my bbt it was low. 
​I have had 3 children yet this time is different bc of the Mirena for 2 1/2 years. 
​I know the only sure-fire way of knowing if your pregnant is to take a test. I guess I am trying to figure if I had a period or not. 
​My question is, has anyone else had these same symptoms after removal?  
​Thanks ladies!
