Input please!!!

My period is due in 4 days but today when I went to the bathroom I noticed that when I wiped there was some pinkish color when I wiped. It only happened the once cuz I’ve gone to bathroom a few times since and nothing. me and hubby have been ttc since 10/2018 with a miscarriage few months ago. So which do you think is more likely I’m bout to get my period or implantation bleeding?

Update: took the test 6-27 around 9pm pic within 5 mins :) praying for sticky bean really pink in person
