What are the chances of me being pregnant 🤷🏻‍♀️

I had “sex” (in and out twice lol) on the 17th and I have quite an irregular period at the moment I got it on the 6th last month and still hasn’t come so few days late if that’s when I was supposed to get it.

I definitely will get a test & check up once my local clinic is open but what are the chances of being pregnant?

Thanks
