Johnson and Johnson vaccine TTC (please people with this vaccine respond)

I know a lot of people post vaccine questions but all the ones related to this one specifically respond saying they got the mRNA vaccine (two dose). Any conceive afterwards or have any complications? Or get it while pregnant?

I only specifically like want this the J&J one because it's the most similar to normal vaccines, like the flu shot, and the side effects are similar to most of our normal vaccines too. I do not trust the MRNA ones because they have never been used on the public, therefore don't know their long term side effects. I am being forced by my job to get the vaccine and want to get BEFORE I actually get pregnant. Planning to get it the same day after I get my IUD taken out. Which is next week.
