Taking prenatal pills ?

Cheri🌹❤

I am not preggo but I've been TTC for almost 9 months I've done everything <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a>, bbt, Cm etc so I decided that I would take a pill to try to help my immune system & boost fertility any thoughts is it safe ?
