Hmm, yeah, that's a girl. It can be hard to tell with dark tabbies because the dark spots on the sides of her genital opening look like testicles from a distance. But definitely a female.
Be sure to have her spayed soon. Kittens can go into heat as young as 4 months (though 5 or 6 months is more common), and you don't want any surprises.
Thank you so much! The coloring was getting me confused I had a feeling she was a she but somebody told me boy when I got her and something today told me to check
