Could I be pregnant?

So these past months I’ve been getting my period every 15th of the month. My last period was about 5 days long. So I had unprotected sex on the 26th of last month, 2 days before my ovulation phase, beginning on the 28th. Although, I was at higher risk of getting pregnant on the 2nd of this month but he did not pull out that time we had sex. So I’m late now 3 days and I was just wondering if there is still a possibility of pregnancy? Let me know your thoughts and experiences please! T.I.A❤️
