Eat spicy during pregnancy

My mother in law say i shouldnt eat too much spicy food during pregnancy as it will cause rash to the baby in the womb. Anyone has experienced it? I eat spicy keropok as snacks, sometimes i eat my meal with chili sauce in moderate. I feel (a bit of) spicy food is the only thing can keep my food down though before the pregnancy i didnt like spicy food at all🥹
