Late period, negative pregnancy test, plan b

Hi,
Welcome to ehealthforum,
The bleeding you experienced after taking the first dosage of ECP could be the withdrawal bleeding (indicating that it has worked), and the second dosage of the ECP taken could be the cause for the delay in next periods. The ECP’s should help in preventing pregnancy if taken within 48 hours of intercourse provided you were not sexually active after taking ECP. Since the ECP contains high dosages of hormones, it can disrupt your normal hormonal and period pattern causing bleeding abnormalities and delay in periods (the effects would be more pronounced if you take repeat dosage). Wait and watch for your next periods which can be delayed. Look out for development of any other new symptoms if pregnancy is suspected. If pregnancy is suspected, or if you miss your periods, or if you have abnormal periods, consider visiting your doctor/gynecologist at the earliest for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). If pregnancy gets ruled out, and if you are not ready for pregnancy, but intend to remain sexually active, you should consider visiting your gynecologist to get started on suitable regular birth control measures to be protected (after your periods). Be regular with birth control use as instructed. Avoid having unprotected sexual contact if not ready for pregnancy, and avoid repeat use of ECP. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle.
Take care.
