This is an issue that you need to address ASAP. It is more than likely the master cylinder or worse yet, you have a leak. This will not get better but the brakes could fail to stop the vehicle and that is clearly not good.
Here is a guide that takes you through some basics that you can check but again, any time you have an issue like this, the brake fluid pressure is getting bleed off somewhere. Either an external leak or an internal one most likely with the master cylinder.
Let me know if you need more assistance. Thanks
