Hopefully y'all can help me. I've been posting this everywhere but haven't got any comments! 
Hello, ladies. This is my first post! I have a question for you ladies. I got the mirena put in April 14th2017, bled the whole time I had it, got it taken out June 12th 2017. I bled from the 12th to the 17th. (5 days is typically how long my periods last)I had unprotected intercourse up to the day I got it taken out and then From the 17th up to now. We decided to ttc but my cycles are pretty irregular so I know next to nothing about them. So first question is would that be considered a period? TMI (too much information) below----------------yesterday I had VERY light spotting. I had pinkish blood on the toilet paper 3 times when I wiped. Then it was gone. I'm feeling kind of crampy. Could that have been implantation bleeding or my period trying to start? 

Also, any advice or experience about conceiving after mirena would be helpful!
