Hi there, I have understood your concern. I will suggest you the best possible treatment options . 1 ) First of all do not not panic. 2 ) If it is feasible to use emergency contraceptive pill like plan B within 72 hours of unprotected sex then it helps you to prevent pregnancy. 3 ) If this period us already passed, then I will suggest you to wait for the onset of your period. In case you cross the date of your period then I will suggest you to get morning s first sample of urine tested for pregnancy. 4 ) If the result is negative, then you need not worry. You can simply wait for the onset of periods or induce the periods with Tab Regestrone 5 mg twice a day for 5 days. Usually periods start within 3 to 10 10 days of finishing the tablets. 5 ) Even if you are pregnant, you can opt for termination of the pregnancy with medicines safely till 9 weeks of the pregnancy under expert medical supervision. 6 ) Missing periods is the most important sign of pregnancy. Your other symptoms can not only be considered as signs of pregnancy. 7) Lastly, I will suggest you to get proper sex counselling done. Use of barrier method like Condom will prevent unwanted pregnancy and STDs. I hope this answer helps you. Thanks. Dr. Purushottam Neurgaonkar.
