So all combined pills have a minimum of a 12 hour time frame in which to take your pill, most have 24 hours. So if you take your pill at 9pm it’s not counted as missed until 9am, minimum. So taking your pill 3 hours later than normal is perfectly fine.
I would recommend reading your pill’s instructions and learning what exactly counts as a missed pill and what you should do if you miss a pill. I would also recommend using condoms unless you are 100% comfortable and confident in relying on the pill as your only method of contraception. It’s not worth the stress.
If you didn’t get a paper copy with your pills you can just google your pill brand
