Should I invest in bonds if I am in my mid 20’s? Roth IRA advice

I am 25, and I opened my Roth IRA a couple of months ago. I have heard that the three fund portfolio is a fairly safe and passive way to save for retirement. However, I have read conflicting information on whether or not I should be buying bonds given how young I am. I know that bonds are typically low risk investments that have fairly small growth over time, and since I have more time to invest, some suggest having a more aggressive investment strategy,

Here is what I am currently invested in: 60% Fidelity S&P 500 Index Fund (FXAIX), 20% Fidelity Total Market Index Fund (FSKAX), 20% Fidelity Total Intl Index fund (FTIHX)

I opted for the fidelity mutual funds so that I could set up automatic investments. I originally wanted to go with the tried and true Vanguard funds, but the minimum buy in was $2,500 for each fund.

Am I on the right track or should I add in bonds?
