20w 5days... Cervix measuring short

leanne • FINALLY after 3 years of ttc
22mm in ultrasound, I was given a 25% of a pre-term delivery... The doctor didn't put me on bedrest or recommend no sex... But he set up a follow up ultrasound next week and possible progesterone needed... My question is can I still have sex? He would have said if I couldn't right?
