Something’s not right and I can’t figure it out why.

So I got a put option on spy. Delta .15, theta .10, Vega .29

Spy is down $2.10 on the day as or right now, and volatility is up today. But the premium on my option only went up by 0.04.

This is the first time where I can’t seem to figure out what’s effecting the options premium.

Pretty new to this id appreciate any help.
