Dear Sunny,
Since you are in childbearing age group, you had sex twice and your periods are over due for 2 weeks, you have to consider the possibility of
pregnancy and try to diagnose pregnancy status. However, your menses are irregular, so you have to keep the fingers crossed till you get the confirmation of diagnosis. However, since your sex was protected sex, hence the chances of pregnancy are minimal. Still better to get clarified and confirmed.
Pregnancy test on overnight first morning urine sample gives best results 8-10 days after missed period. Your periods are delayed by 2 weeks. So this test should give reliable results about your pregnancy status. However, due to irregularities in your menstrual cycle, it cannot be relied up on if it is negative.
The best option for you should be
Beta hCG test. This test gives reliable results even few days before missed period. I feel you should go for it.
If you are not pregnant, you may take tab.
Deviry for 5 days and within 4-7 days, you should get withdrawal bleeding.
However, considering your
nausea and
vomiting, the question is whether you can retain these pills in the stomach. Therefore, please report to your doctor to control this gastrointestinal problem before you take Deviry. Even if you are pregnant, nausea can be attributed to it as
morning sickness, not
diarrhoea for which you have to take some treatment. If you can tolerate oral fluids, oral rehydration solution after each motion should help you. Still if it is not controlled within 24-48 hours, you should report to the physician.
I hope this helps you.
Dr. Nishikant Shrotri
