My iphone 15 pro battery health has dropped to 93% in just 300 cycles. I have just used my phone for 8 months.

is this normal or do i need to get it checked ?

Yes, completely normal. You can expect about a 1% drop in battery health for every 50 cycles (on average). 303/50 = 6.06. So a drop of 6 - 7% would be normal after that many cycles. It's likely higher than 93%. For example it might be 93.9%, but when posted, it rounds down to 93%.

Your iPhone is expected to drop about 1% battery health per 50 charge cycles on average.

After 300 charge cycles, you should be at 94%. Note that your iPhone rounds down any tenth of a percent battery health. So if your iPhone's health is 93.9%, it would display as 93%. Also note that the battery health decline is subjective to many other factors such as usage and conditions and varies per person.

You only need to get your battery checked when it reaches 80%. That is when you will need the battery replaced. For now, your battery is normal.
