RH- and spotting?

Ashley
I'm 9weeks and 3 days, I found out 2 weeks ago I'm RH-, after using the washroom this morning I had one little spot of bright red blood, wiped again it was light pink and went to pee again 15 mins later and nothing. Should I go to the ER and see if I need a RH shot? Opinions ladies!!!! 😳😳
