Is it likely for me to be pregnant if I had unprotected sex about 3 weeks ago, the guy i was with didn't ejaculate...but I was still worried so I took the moring after pill...and now i think it's very close to the time of my period. My breasts are very tender and sore and I am also expercing cramping...which are also signs of pregnancy...and i am also spotting. I took a home pregnancy test today and the result was negative. However I am still somewhat worried. Is it likely that I am pregnant? or that I just havn't gotten my period yet because i am stressing myself out?
