Pregnancy after IUD removal

Hi ladies. My husband and I have been trying for our first child together since June (4 cycles) and haven’t had any luck. Many of you may know exactly what I’m going through and others may have been trying for much longer. I had my Mirena removed in June and I know so many people that have gotten pregnant right away after the removal. I don’t believe there are any lasting effects after Mirena. However, we’re not pregnant yet. Please share your experience if you had a Mirena removed and went on to get pregnant whether it was right away or it took awhile. I’m hoping that other women have been through what I’m going through but ultimately ended up pregnant even if it took a year or so. I know at 4 months I shouldn’t be discouraged but we have used OPKs the first 3 cycles and started temping for the 4th. I just need to know that it’s not out of the norm for it to take this long even with knowing when I ovulate every month.
