When do you think I can have sex again?

I am 7w4d currently and Last Friday I had some pink spotting and was crampy and called my doctors office to let them know and see if they wanted me to do anything and the doctor just told me it was normal and I let her know I had an ultrasound scheduled for Tuesday (today) and she also told me not to have sex. Well I got my ultrasound today and baby looks perfectly fine. Do you think it’s ok to have sex again? I’m assuming I should be good to go and I don’t really want to call my doctors office just to ask if I could have sex now 🙈
