What is the possibility that I got pregnant?

Hi I come with a question what is the possibility of becoming pregnant. On the night of February 19-20, I had a relationship in which we removed the condom and could get to the ejaculation in the middle. It was the day after the end of the period and I did not have fertile days. I took the tablet day after about 40 hours. After about 5/6 days after taking the tablet, bleeding appeared too scant for menstruation but too abundant for the implantable tribe. Bleeding lasted for 5 days. Yesterday I should get a period but I'm still waiting impatiently. My cycle for a few months lasted regularly 28 days. Yesterday I started to be bolewac underbelly and nipples themselves. He's very nervous.
