White smoke from tail pipe

Hello everyone, have a 2008 g37 coupe with 156,000km on it and recently found thick white smoke when I first start the car. I never noticed it before since it was winter but now that it's warmer it's much more noticeable.It smokes up for 10 seconds like if I sea foamed the car and then returns to normal.

I am not sure if it's a head gasket issue or not...

-Car has not over heated, I usually make 20km trips to and back from work
-no sign of coolant leaks on the floor
-I have been trying to keep track of the coolant level since I first noticed a week ago

From my lack of mechanical expertise I am assuming it's a slow head gasket leak but would like a second opinion.

Side note: are any of the head gasket sealants in a bottle any use? was considering a bottle of blue devil

Thanks all!
