37 female mom of 2 memory

I am a 37/yo mom of 3 and 5 year old. I work full time and am a mom. For a while now I have been feeling like I can't recall simple words. Ex the other day was walking with my family and couldn't think of the word driveway. I don't sleep well but I am wondering if anyone has gone through this? Not sure if this is nothing or something I should look into more. TIA
