Should I be worried or go with the flow..

I feel kinda worried about when it's time for me to deliver my baby .. I'm a FTM and I feel like I should have done things differently. Like I'm almost 30 weeks and I don't have a Obgyn. Or a midwife. The clinic I go to for prenatal checkups just has nurse practitioners , They are not real doctors.. Idk if I should look for an OB Or if it's to late.. If I should continue to do my check ups where I currently go .. And when the time comes just go to the hospital?
