Hi there, I have understood your concern. I will suggest you the best possible treatment options.
1 ) First of all do not panic .
2 ) As you have mentioned that you have taken
emergency contraceptive pill within 24 to 72 hours of unprotected sex act, and you also get period on September 28th. So the cycle of August to September, there was no
pregnancy.
3 ) Now, from the cycle starting from 28th September, did you have unprotected sex act in the fertile period t the cycle, means between day 10 to 20 of the cycle. If not , then you need not worry about the pregnancy.
If you had unprotected sex in this period, then I will suggest you to get morning's first sample of urine tested for pregnancy. In case of doubt blood
beta HCG test and USG will be of help.
4 ) Even If you are pregnant, you can opt for termination of the pregnancy with medicines safely till 9 weeks of pregnancy under medical supervision.
I hope this answer helps you.
Thanks .
