Over-the-counter prenatals or Preg Vit folic 5

Hey ladies! BFP this a.m. I have been taking an over-the-counter prenatal while TTC and the last month I have add an Omega 3. I did take a prescription prenatal, PregVit folic 5, when I was last pregnant (ended in mc). I was wondering your experiences / preferences. The PregVit is two tabs, one a.m., one p.m., one is high folic acid, the other high calcium, however, in comparison to my OTC prenatal, it doesn't seem as well rounded. The other vitamins and minerals are substantially lower. I know folic acid is important, but the difference is striking. Also, would you continue taking one Omega 3 in addition to a prenatal? I will ask my doctor, but wanted your ideas too.
