Pink discharge during early pregnancy?


We just found out we’re expecting!!! :) my las menstrual cycle was dec 1st and I got a bfp on Thursday right after Christmas. My hcg levels came out 308 on Saturday at the dr. Today we had sex and I wiped and I had pink on the toilet paper I’m worried we hurt out little poppyseed ? Please should I be concerned ? Should I go to the er?
