Pre-natals?

Ok, so I need some reassurance. I have been feeling extra guilty about not taking my prenatals regularly. I took them for like a month before getting pregnant, all the way up through the end of my first trimester. Since then, I've had a tough time with them. I can't seem to swallow pills without gagging and the gummies started grossing me out after the horrible morning sickness. Basically I have taken them sporadically.
My question is: anyone else on the same boat? Or anyone else with past pregnancies have similar stories? So far, baby looks healthy and shows no obvious signs of physical difformity, but could there be mental issues? 
The guilt is just killing me thinking I may have harmed my innocent baby.
