Light bleedingšŸ˜©

Im 5 weeks. I woke up like at 4 am because i was having nightmares dreaming that i had stomach pain. So i woke up got up to the restroom pee and when i wiped there was blood pinkish red and i looked down and there was a little bit of splatter red(blood) on the toilet. Should i bee worried? Should i go to the doctor. I never experienced this with my first pregnancy.šŸ˜©
