Prenatal Vitamin Struggle...

Is anyone else having trouble with their prenatal vitamins making them so sick?!?  I tried taking them at night....ugh. I've switched to taking them with lunch and then the whole second half of the day I feel like crap.  I don't remember having this issue with my first son! 😜 I've tried Nature Made prenatal from Costco, I'm currently taking Rainbow Light, what I took the first time...and I tried some gummy Vita something from target...any suggestions or other brands would be appreciate.  Have a drs appt Thursday...gonna ask then too!
