Straight up 'no ****ing way' dude. Why would you ever entertain the idea of taking some unapproved **** during pregnancy? How would you feel if there was a complication? Would you wonder if it was because of the stuff you took? Would you be sure?
Take a good prenatal multi, high quality PURE fish oil, and lots of good fresh food, fruits, and veggies. This ain't rocket science, or birthing's first rodeo. Keep it simple, stupid.
