Blood in poop

Krystal

I recently switched my daughter to whole milk about 2/3 weeks ago, she’s 1 year and 6 days now and as I was bathing her she pooped in the tub. As I started to clean the tub I see blood in her poop, not a lot, idk if some got washed away but she’s never had blood in her poop before so of course I’m concerned. The poop was really hard so I’m thinking she was constipated. What should I do? I have work in 2 hours but scared to leave her.
