Do your prenatals make your MS worse?

I have had a good day or two of not feeling morning sickness. Those two days I had completely forgot to take my prenatal vitamins. I took them first thing this morning and now I feel like my morning sickness is back! Is it coincidence or do prenatals actually play a role, ya think?

*P.S. setting reminders on my phone for taking the prenatal pill doesnt work for me. I just ignore it if Im busy and forget it.
