Please help

Okay so here’s my issue: I am not on Birth control and I had sex for the second time. First time was back in October and I didn’t let him finish because I was so scared. I did not get pregnant and everything was fine. The condom was okay and everything. I did it again with another guy, we finished and I went home. I found the tip of the condom shortly after. I rushed to the store 2 hours later and took the levonorgestrel contraceptive pill.... it is now Tuesday and I don’t get my period for another 10 days.... should I be worried? Should I trust the pill? And I began having a nipple discharge... what’s wrong? NO ONE KNOWS AND I DONT KNOW HOW TO GET BIRTH CONTROL WITHOUT MY FAMILY KNOWING. THEYRE VERY RELIGIOUS.
