Pregnancy Info HOME

I'm gonna get strait to the point and hope someone has some answers. I had Unprotected s_x with my boyfriend on NOV. 10. He had c_mmed in me for the first time. I was to be expecting my period around DEC. 13. On DEC. 13 My boyfriend wanted me to take Emergency Contraceptive pills, i had taken it only once before months before. We got the pill and I took it on DEC. 13. I waited to start my period. Today (DEC 15) I spotted a Tiny bit so i thought maybe i was starting my period. I had a tampon in almost all day and when i went to change it there was nothing on it??? what could this mean? could i be pregnant even though i took the pills? and if i could be, does taking the pills give possible complications to the baby? please any type of answer would help. Also has it been long enough that i could get a pretty accurate text result from a home test?
