Anyone been in my shoes before?

I was wondering if anyone has had the Mirena and had to have it taken out because of pre-cervical cancer and TTC shortly after having a CKC (Cone Knife Cut?) I had to have mine taken out April 13 for surgery and we've been TTC #5 since we got the go ahead from doctor. AF was due 7/10 and hasn't came yet; does anyone think I should wait to do a test or go ahead? I think I am going to get a test but wanted to see others opinions in this matter. Thank you
