Birth control pills

Has anybody ever felt like really tired on birth control? I am on my 2nd pack about to start my 3rd week soon & then I will start taking the white sugar pills. I just feel more tired than normal. I've been really stressed lately too much as been going on but idk if that has to deal w. me being so sleepy. It could be because according to my period tracker I am fertile and will ovulate until next wednesday but idk. I also have alittle shortness of breathe and that happened with the first pack on my BC pills... I did go to the doctor about it but she said my hormones are all over the place and that I need to give it 3 months so my body can adjust to it. Also I didn't start feeling like this AGAIN until after my period on the 1st pack of birth control pills, I felt fine when I was taking the white sugar pills because they have no hormones in them.Also my appetite has decrease as well I really don't eat as more when I started taking BC. Should I just wait it out until my 3rd month to see if anything gets better?
