At that time, you will be given a pregnancy test if menstruation hasn't begun. If the test is positive, you can discuss the advisability of carrying the pregnancy to term with the clinician. The prevailing medical opinion is that the Morning After Pill will not cause birth defects. However, there are a few studies to the contrary which should be discussed with your health care provider. Women who have health problems that prohibit them from taking regular birth control pills cannot take the Morning After Pill.
Side effects are infrequent.
When they do occur, the most common ones are nausea and vomiting, breast tenderness, irregular bleeding, and headaches. All are usually mild, and stop within a day or so after treatment. If a woman vomits within an hour after taking the Morning After Pills, she must get in touch with the clinician to see if she needs additional pills to make up for the ones lost in vomiting. Danger signs to watch for include chest or arm pain, dizziness, fainting, severe headaches with vomiting, muscle weakness or numbness, speech or vision disturbances, abdominal pain, yellowing of the skin or eyes, breast lump, or severe depression. If you experience any of the danger signs, you should seek medical attention immediately and call us as soon as possible.
