Did anyone struggle to get pregnant after Mirena?

I had my first child at 19 years old and had my 2nd child 28yrs old. I am currently 30 years old, soon to be 31. I hear when you turn 30; the percentage drops a bit to fall pregnant; I put the Mirena in march 2019 and got it taken out this year in January 2021. The whole time I got a small bleed and light only three days a month. It’s been now almost six months since I have been out. My period went l straight away back to normal 4 to 5 days medium bleed a month. Now I find I’m struggling to get pregnant? has anyone else had issues or similar after Mirena out to fall pregnant, or did it take extra time… thank you

It took me a year to get pregnant after taking the mirena out. I am 28.
