Constipation vs taking prenatal vitamins

The constipation, as I am sure most of you know, is ridiculous! I've started taking so softeners but they don't even work. The only way to go is to not take my prenatal vitamins for a couple days. Sometimes it only takes one day. Is this dangerous? Is it ok to skip a few days of vitamins and then go back on them? Sometimes I just gotta go! Maybe there's a better vitamin option? Any suggestions?
