I just stated a higher dosage of birth control a few days ago. i have been constantly hungry and my uterus seems to be a little sore , is this normal?

Oral birth control ?: The most common problem with oral bcp use is the failure to take the active pills punctually. Even minor irregularities of several hours difference in the time taken will cause withdrawal effects resembling the onset of a menstrual period, which also may include spotting. Stopping the current pack of pills, waiting five days, and starting a new pack with attention to punctuality will help.
