Hi, this is for my friend, she needs advice for she is experiencing spotting after sex. She said that she had sex with her partner one week before her menstruation then experienced spotting. She said that this happened to her only twice last january and march. Spotting only happened when she had contact with her partner before period. She had her period last feb. 24 and said that her period is regular. Is it normal to have spotting after sex before period or it is caused by a serious condition? Thank you
