Go to the ER?

Hello! I’m 36 years old and got my BFP Sunday morning. I had sex with my husband last night and started spotting watery pink/red. I have lightly spotted today when wiping. Nothing on my panty liner. Should I go to the ER and be checked or just wait it out until my first Dr appointment at 8 weeks? I’m approximately 4 weeks and 4 days based on my ovulation date. Thanks for your help!
