Sis, kung may unusual spotting or bleeding, please go to your OB or emergency right away, better safe than sorry sa early pregnancy!
Otherwise, normal lang yan, we all wipe after using the bathroom. Just make sure you're wiping from front to back para avoid infection, and use clean tissue. A few of us moms always do this lalo na pag pregnant kasi mas prone tayo sa UTI. Kung may pain, unusual discharge, or bleeding after, that's when you need to see your doctor agad, okay? Take care ng sarili mo!
