TTC after Mirena--general questions

I am brand new to all of this so I will share my story. I have to kids 8 and 11 and they were not planned pregnancies. I am now 33 I was on Mirena for a total of 5 years, no periods. I got my Mirena removed on 6/19 and did not have period until 7/29 and it was 3 days. It is pretty much the same since before Mirena. My fiancee and I normally have sex every night or every other night depending on the mood. According to this app I am ovulating right now and we have been having sex twice daily or every day. Has anyone had experience getting pregnant quickly after Mirena? Any advice or any experience would be great. I am trying to chill out and not up my expectations but since I am now actively trying it is all I can think about.
