Prenatal vitamins and nausea

Kristin • I`m 29 Trying for our first. Have been waiting a long time to start trying and so anxious about it. Had Mirana removed!
This is my first month TTC and just started prenatal vitamins as well. I make sure to take them mid day after lunch so with food. I have had mild nausea during the day recently and it gets worse at night. Has anyone else experienced this their first month TTC as well as with prenatal vitamins?
