Birth control pills: freaking out

Im on my second pack of pills (I started my first pack in mid December I believe) and I’m freaking out because I’m on week 4 day 3 of the green pills and I still don’t get my period. I’ve been taking them Every day at 9:30pm sometimes 9:45-10:00 but I make sure I don’t skip days. Can anyone share your experiences with birth control pills. I was told I could ask my dr to see if I’m fertile is that true ?
