I was put on birth control (the pill) Thursday January 19th,  I started it that night @ 9:58 pm and I know your supposed to wait till the first day of your period or the Sunday rule but I Read that you didn't have to. So anyways I've been having terrible symptoms, I woke up Friday morning with nausea and my head had a terrible pain. I didn't eat anything all day because I felt like I was going to just throw up. Then last night I kept waking up to awful Stomach pains. I can't get any of these symptoms to go away and I've just been so miserable. I have been exactly on time Every night so far. I also am on the pill only because they had to order an iud, so I'm glad I won't have to be on it for that long. But are these symproms normal? Please help me out here.
