Anyone ever get sick after taking prenatals?

Ashley
So I just started taking a new prenatal this morning. It's the kroger brand prenatal multivitamin. About 15-20 minutes after I took it, I started throwing up out of nowhere. I'm trying not to think too much into it, because I think it would be way too early to experience pregnancy symptoms. I think I'm about 4 DPO, so I'm just wondering if anyone else has had issues with prenatals. Just FYI We are TTC #1, so I've been analyzing everything as a symptom, it becomes so frustrating. I have had light to moderate cramping everyday since I ovulated, and way more tired than usual. My period has been weird lately, and last month, I started 3 days early. Any advice is welcome! I'm new to this!
