Foundation shade help

So I really like loreal pro glow foundation and I’m afraid tog et the wrong shade. I been using shade 203 but it seems to be slightly too dark/too pink I’m not sure if I should get a shade underneath it (202) or jump to shade 105 since it’s got a different undertone but wouldn’t it be too dark? I need help lol i feel like my face don’t match you probably can’t tell in the photo but I can in person (off topic)
