Having trouble 😢

This post may seem selfish to others and make since to others but, I have three healthy beautiful daughters 9,7, and 3! After my three year old I got the idu Mirena and had it taken out about a year and a half later do to not liking my cycles and not being on track. So November 2017 I had it out and my husband and I said why not let’s try for our last well here we are 7 months later and nothing! I’ve never had an issue before he could look at me dirty and I would be knocked up lol! But I’m losing hope.. is there something wrong? Did the idu give me an issue? I haven’t talked to my doctor yet he took my idu out I had a normal pap afterwords. Any help or feed back from women and moms that have had this issue? I don’t want to give up but I also do not want to keep breaking my own heart hoping it’s going to happen if it doesn’t.
