According to my calendar, my peak day of ovulation was on the not so careful day of February 9th. (I didn't realize it at the time) Anyway, as of right now I am displaying a lot of pregnancy symptoms including: no period (yet), nausea, heartburn, gas, indigestion, frequent urination, weepiness, fatigue, mild cramps that feel like mild menstrual cramps, and swollen but not painful breasts. So I'm having all of those symptoms but the test keeps coming back negative.
