Mirena/endometriosis successful pregnancy???

Courtney • I am 25, married to the love of my life and we have a 6 yr old daughter. We are hoping for a boy this time!
I have endometriosis and I of course was told 10 years ago I wouldn't be able to have children. I have a 6 year old daughter, on her 5th bday I got a Mirena taken out and a second one Put in. 9 weeks ago I got the 2nd one taken out because we want to try for a second baby. My daughter was the best oops in the world ;) 
​I am wondering how many woman successfully have got pregnant having endometriosis after having a Mirena remove and how long did it take. My Mirena came out and I had a monthly 28days later, first one in 10yrs, and the my 2nd monthly 30 days after the first so my "cycle" seems to be ok.
