Nature made recall?

So I know that prenatals are not on there, but when I heard about the recall it made me think. I started taking them the day after I found out I was pregnant, I had the worst diarrhea and stomach cramps ever. And it was always after taking my prenatal! The stomach cramps were so intense and I'd always have to poop afterwards. I ended up miscarrying 4 weeks after I found out I was pregnant. coincidence or not?
