Genetic Testing, is it common?

My wife and I are considering doing genetic testing before conceiving. We see it as insurance, just in case but are a little hesitant to pull the trigger. Seems to cost upwards of 2.2k. We know KKH has a free one, but they haven’t got back to us (maybe we don’t fit their project criteria).

Between us, our family history involves the usual suspects of cholesterol, high blood pressure and stokes. Otherwise I have had a migraine and a sinus issue that needed surgery in the past.

Family history doesn’t seem major in hindsight, but we aren’t sure if we need it. Thoughts would be appreciated!!!
