Answer
Hello Jessica,

I cannot determine the sex if it is that small especially without a picture.  Males are usually smaller than females though, & have larger claws & longer tails, too.
However, after 4 years, if it is only 3 inches it is malnourished.  
Do you provide UVB lighting & a basking light for it?
They need calcium on a regular basis along with UVB exposure or their bones will become soft & can get softshell.  
They do need veggies, greens & fortified turtle food.  Fish food is not adequate nutrition for turtles.  Keep in mind that commercialized pellets should only make up a small portion of their diet.  The large majority of the diet should be comprised of veggies & greens with fruit a couple of times per week.
Right now, your turtle is too small to consider breeding, no matter what sex your turtle is.
