Pre pregnancy check up?

So I have never gone to the doctor to get a check up before trying to have a baby because last time me and my husband kind of just winged it and I got pregnant in a month and lately I haven’t had any luck with getting pregnant is it normal to go to the doctor or the Gyno to get everything checked to make sure I’m in the clear and healthy to get pregnant again is that like a thing? LOL
