Can I be pregnant and menstruating?

Hi doctor! I would like to know if it takes too long to be able to get pregnant, I took contraceptive for 6 months and I stopped for 3 months only before before I had been missing the pills I spent 2, 3 days without taking more I did not get pregnant, in the other month I stopped taking it for complete and having more relationship do not know if I got pregnant my period came more doubts I did not do the beta exam because fear of the result will be that I can be pregnant and menstruating?
