Could my twice-monthly periods and sensitive breasts indicate pregnancy?

Hello. I have a problem with my menstrual cycle, for about 2 years it has been coming twice a month. For a year and a half we have been trying to have a child so we have regular unprotected sex. The idea is that on Sunday (day 17 of my cycle) I had a short bleed and then nothing. I had sex on Sunday evening and not a drop of blood flowed, it's the first time this has happened, besides that my breasts are quite sensitive. Do you think it could be a pregnancy or just another hormonal imbalance?
