spotting after sex

Is it normal to spot after sex ? I am 9 weeks pregnant 
Me and my husband just had sex and when I wiped there was a bit of pink spotting after I kept wiping it went away I also have cramps 
It makes me nervous about miscarriage 
I do have an appointment with my doctor on Monday should I wait till then and let her know ? Or should I go to urgent care to check on baby ? 
Sorry if it sounds exaggerated but being pregnant I just want my baby to be ok
