Birth Control

I recently began taking birth control again. I've taken it consistently since I've been back on it. (4:00 every night) I haven't gotten to a regular doctor yet and my days have been hectic I was wondering about personal side effects others have had. My hair seems to be falling out immensely (I don't know if I'm that stressed about things or what!) I've been SUPER moody, moodier than I typically already seem lol! My period also seems to have lasted a lot longer than it did before. (Went from about 3-4 days to almost a full week) I stopped bleeding as heavily but I've still been spotting for almost three days!! Please any advice helps.
