Hello dear
I understand your concern
No
contraception is 100 % effective in preventing the pregnancy.
Unwanted 72 is 95 % effective if taken with in 24 hour of sex.
Withdrawal bleeding is not occur in all cases.
lower back pain,body ache,headache,fever,nausea,
joint pains could be a hormonal imbalance caused by unwanted 72 or pregnancy.
Unwanted 72 also cause delay in the period by 8-10 days.
If period will delay by the 12-14 days then go for urine pregnancy test and or Blood HCG test to confirm the pregnancy.
Frequent use of the unwanted 72 and
misoprostol is not safe.
It cause frequent
miscarriage, hormonal imbalance,
infertility issue, menstrual irregularity.
Hope this may help you
