Ok my lmp
was 11/18/12 I have a perfect 28 day cycle. According to an ovulation calendar
I was most fertile on days 28~1, ovulating on days 2&3. Had unprotected sex on 28, 1, 2, & 4. Now experiencing sore breast, lower back pain, cramps, hot flashes, and mood swings. Due to start on 12/16/12. I don't know if this is all in my head but could I be pregnant? I know its too early to test. Just concerned.any responses would be greatly appreciated.
