Hi,
Your symptoms could be due to
hormonal imbalance. You used post pill two time with in short period. Post pill contain high
progesterone and cause hormonal imbalance. It also cause earlier period, delay in period by 1-3 week and excessive bleeding can occur.
So I think it is most commonly due to side effect of pill.If period will delay by more than 2 weeks form normal expected period date then go for urine
pregnancy test and or blood HCG test to confirm pregnancy. Do not use Post pill as regular
contraception as it cause hormonal imbalance, menstrual irregularity,
infertility issue. Use condom in future to prevent unwanted pregnancy.
Avoid stress, take healthy diet, drink plenty of water,do regular exercise. Avoid alcohol, high caffeine and high slat.
Hope this may help you. Contact further if follow up needed.
Best regards,
Dr. Sagar
