Conceiving during Luteal Phase??

Is it possible to become pregnant during the luteal phase of your menstrual cycle? My boyfriend ejaculated inside of me a few times during that time frame and my period came the following week? Would that affect anything? The app said it’s a 3% chance likelihood of pregnancy so I wonder if this has happened to anyone before!

We are waiting to see if my next period will come in a couple of weeks... kinda hoping to be pregnant.
