Does anyone else take these and suffering with really bad diarrhoea?

You’re supposed to take them with your “main meal” I don’t know about anyone else but I struggle eating a main meal so maybe that’s why they are causing me to have a really upset belly the next day?

I decided to not take them for a few days and just take folic acid and was fine, took pregnacare yesterday and today it’s not good!!!

What’s everyone else opinions on vitamins ect? Could they be causing the issue or just pregnancy related?
