This is normal. Your credit score could change daily depending on how often your credit report is updated. Your creditors and lenders are continuously making updates to your credit report throughout the month. Each time you check your credit score, it's recalculated based on the information in your credit report.
Most companies will allow this every 3 months or so. When you receive an increase in scores, as long as you use your credit wisely and don't charge balances more than 30% of your limit (i.e. $150 on a card with a limit of $500) you will have a better credit/debt ratio and may see some increase in your credit scores.
