Does plan b mess up your cycle on birth control
Welcome to ehealthforum,
Since the emergency contraceptive pills contain high dosages of hormones, these affect the hormonal and period pattern causing delay/changes in periods. If you have noted changes in menstrual period cycle, you should consider visiting your doctor/gynecologist for further evaluation to look for the underlying cause for your changed period pattern/missed periods. Treatment as appropriate (based on examination findings and investigations results) would be started to help you get your periods and regulate your periods. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet and lifestyle.
