if its sprong now what was it 3 mouths ago

It depends which month it is in spring, unless you want the specific season, which is summer

 

summer is your answer

I assume you mean

if its spring now what was it 3 months ago

 

In Australia it is clearly defined.

Winter comes before spring.

So the answer is Winter.

 

Our seasons are defined by months, I think in the US it works differently.
