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 there is history of unprotected sex act, I will suggest you to get morning's first sample of urine tested for
pregnancy, once you cross the expected date of the cycle.
3 ) 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 guidance.
4 ) If your pregnancy test is negative, then your symptoms can be due to PMS -
premenstrual syndrome.
In that case I will suggest you Tab B LONG F,
PRIMOSA,
Vitamin E 400 mg each one at night for 3 months.
Also opt for a healthy diet and regular exercise regimen. Avoid deep fried foods, bakery products and refined sugars.
I hope this answer helps you. Thanks.
