I am a 28 day cycle woman, normally ovulating every 14 days. My last regular period was on May 23 2011, I had unprotected sex on May 30th, My period came for 1-2 days with very light spotting. I have many of the normal pregnancy symptoms. Such as; nausea, fatigue, breast/nipple soreness, abdominal cramping, weight gain, increased appetite etc. HPT said neg twice, one had a faint line. Do you think i could be pregnant?
