Extreme TMI ( Blood on totilet paper )

So this has been happening for a couple of weeks when I past a bowel movement for the first couple of weeks i had a sharp pain when pooping and when I wipe that’s what i see I get no pains throughout the day or nothing I drink plenty of water no sure if it helps but I had a baby 4 months ago this has never happened before now when I poop i don’t feel any sharp pains .. any ideas of what it could be and if I should go to the doctors ? Thank you in advance
