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 used media For egg formation, I will suggest you to wait until you cross the expected date of your period. Only nausea can not be considered as sign of pregnancy. 3 ) In case you cross your dates, please get morning s first sample of urine tested for pregnancy. If test is positive, please follow with your treating doctor s advice. 4 ) If the results are negative, 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 days after finishing the tablets. I hope this answer helps you. Thanks. Dr. Purushottam Neurgaonkar.
