Is it good to still have unprotected sex if you're pregnant?

Sexuality: I am not sure what you are really asking? Good? I don't think we use the words 'good' or 'bad' in medicine. When one considers unprotected sex we are talking about the risk for pregnancy or for sexually transmitted diseases. If you are pregnant then that is off the table. If you trust your partner and there is no risk for stds then that is also off the table. That sounds like monogamy.
