Should I ttc this cycle or not?

Today would be 4 weeks after my miscarriage and I finally got my first period. My app says I'll ovulate on the 16th. I also happen to get blood work done on the 16th to see why I keep having miscarriages. If my blood work comes back normal then they want to fill my uterus with dye and look to see if there is anything abnormal. The thing is I'm suppose to ovulate around the 16th so If I get pregnant this go around I won't be able to get the dye testing done. I just wanna be pregnant so bad and not be to far behind my original due date that was suppose to be May 2nd. It's such a hard choice to make. What is your option on whether to wait or ttc this ovulation? I will be getting the blood testing done without a doubt
