2 years and nothing

Me and my husband have been trying for 2 years to conceive. I previously had the Mirena for 4 years (I DO NOT RECOMMEND). Ended up being hospitalized due to recurring ovarian cysts and had an episode where I thought I was having a miscarriage, there was soooo much blood. After that, I had my doctor remove the device. We have been trying ever since, and nothing. My period has stuck to its schedule perfectly. For the first year and a half, we were adamant about trying very day(except during my period days) but now, it has been over 2 years; I am losing hope of ever becoming pregnant, which has caused me to back away from trying as much. Any tips? Has this happened to anyone else?
