Growing, Growing, Gone?

Now that I've run out of prenatal vitamins finally, should I get more of the same, or just switch to a regular or women's formula vitamin? And if I want to maintain my relatively long nails, should I add a calcium supplement with any of the above? I've begun taking my nails for granted since taking prenatal vitamins for so long. I forget how long they are until someone compliments them or I actually need to cut them because the length is interfering with day-to-day tasks! I wish I had the time and motivation to keep them polished too. I brought all of my chosen polish stuff with me on vacation last weekend thinking I'd get them done on the long car ride...but it didn't happen.
