pls. shed a light on this. first day of my last period was on 10/3 til 10/5. on 10/5, i engaged to unprotected sex. on 10/15 and 10/16, it happened again, but i took the levonorgestrel pill few hours on 10/16. five days after taking the pill, i had a period like bleeding that lasted for 3 days. had sex again on 10/23 with condom and again on 11/02. i took another pill on 11/03 and a preg test on 11/4, that came negative. i have irregular mens cycle so im quite confuse right now as to when will i have my period for november. is it okay to take two pills on the same cycle? is there a possibility i can get preggy. as of now, i still dont have my period. pls. help. thank you
