My Fiance came home that week, and we had unprotected sex. Immediately I started feeling "different"! And I still am. Cramping on lower and occasionally right and left abdominal, lower back is killing me, my breast are extremely full,HEADACHES, and sometimes nauseous, occasional cramps in my legs, VERY TIRED, short of breath, and lastly no AF! i'VE taken numerous pregnancy home test, and ALL NEGATIVE. : ( Im not stressed so where is AF hiding at???
