does my credit score go down if i check it

No, checking your credit score yourself does not lower it. When you access your own credit report, it is considered a 'soft inquiry' or 'soft credit check'. Soft inquiries have no negative impact on your score. A drop in your score only happens due to a 'hard inquiry', which is when a lender formally checks your credit after you submit an application for new credit like a loan or a credit card. Checking your score regularly is a responsible financial habit.
