Discharge questions

Twice today I have white discharge with a tiny speck of blood in it. I’ve never had discharge like this before and I plan on calling my obgyn to make sure this is normal was just wondering if anyone else had any idea what this means and if it’s normal? This April I will have an iud for a year. I had a baby a year ago also. I’m not sure if any of those have anything to do with why my discharge looks like this but I figured it would help knowing those things to give me your opinion. I do not have a picture of it tho.
