Pineapple during pregnancy - I just heard not to eat it??

Jg • Pregnant with TWINS after mc in April 2015 -looking forward to this journey - trying my best not to be anxious
So I had a tiny amt of pineapple today then for some reason I googled it and it says not to eat it? I thought fruits were in the safe zone to eat lol am I the only one who had no idea?
