Microgestin

So for the past week and 2 days I started taking a birth control called Microgestin which is the one my doctor gave me.... Is anybody else taking it?! And if so how was your first time taking it ? Keeping in mind this is the FIRST time I EVER take a birth control.... I felt horrible, light headed, stomach pains, I felt nauseous... Headache I just felt bad, then for the second day and the rest of the week till today I felt fine ..... I just want to know.... How was your experience?
