Thank you for your comment, I will take it into consideration :).
Sometimes breasts get tender and hurt when we ovulate. I would wait a few more days and if your period doesn't come, take an at home pregnancy test. If it's negative and your period still hasn't came, you should probably wait a few more days and re-test, or go to the doctor. I had a very late period, and kept taking pregnancy tests and they kept coming out negative, and went to the doctor and found out I was 6 weeks pregnant. But I doubt that you are pregnant, good luck!
