I have liquid coming out my nipples and i had intercourse could i be pregnant

You : You should have a pregnancy test, and if it is negative then you should have other types of blood tests such as prolactin. I don't know your age but you should have a complete breast examination also, and if you are at the appropriate age then you should have a mammogram. It is unusually to have this symptom (galactorrhea) and you need a medical evaluation.
