Hi. thanks for asking in Healthcare Magic.
Postinor is Levonorgestrel
. It prevents conception if taken within 72 hours. It prevents the implantation
Taken as a contraceptive
, it can result in vaginal bleeding along with nausea, headache, dizziness, fatigue and breast pain
side effect. Your stomach pain and spotting are due to uterine contraction.
Drugs like Mafenamic acid and Tranexamic acid
will stop the spotting. Combination of these two drugs containg Mafenamic acid 250 mg and Tranexamic acid 500 mg are available as over the counter drugs. You can take it twice a day for 3 days to control the spotting. If the bleeding continues even after that, you should visit your treating Dr for further course of treatment.
I hope this is helpful to you.
