Is this constipation? Poop pic

Maria

Looking for some advice on this. My baby is 2 weeks old and was pooping fine without straining until 2 days ago. Her poop looks like this and she goes after every feeding (enfamil gentlease) when she goes she strains but other than that shes not fussy and sleeps fine. Her doctor didn’t seemed worried over the phone but im not sure if I should be or if there’s anything i can give her. Any advice is appreciated!
