One tiny spotting 30 weeks.

Last night simply while wiping i noticed a very tiny blood spot not bright. I am not even sure if it came from vagina coz i dint initially notice it. But when i turned the paper before disposal i just saw it. Baby is active ever since no other signs and i have been monitoring ever since. Since it was very tiny and onetime event and also me being unsure i decided to wait till Saturday for my regular ob appointment. Guys any insight if i need to get it checked immediately or wait and monitor. Also any similar experience?
