Thanks for query.
You have taken prostinor 2
which is emergecy contraceptive
pill,but you have to take this 2 tab in 12 hrs. apart as early as possible after sexual intercourse or with in 24hrs.
I think you are not pregnant.
You should consult a gynae because your dose ofmedication not proper.
Spotting is side effect of medicine also.
You should go for USG and blood test
As such this drug is not having any major side effects but if pregnancy
you should immedieately stop this medication.
