Hi there, I have understood your concern. I will suggest you the best possible treatment options.
1 ) First of all do not panic.
2 ) If you have history of regular cycles and now even with the history of unprotected sex act, your blood and urine tests for
pregnancy are negative, you can assume that you are not pregnant.
3 ) In such case, your symptoms can be due to PMS -
premenstrual syndrome. In that case, I will suggest you to indulge in a healthy diet and regular exercise regimen. Include more portions of fruits, salads and vegetables in daily diet. Drink plenty of water in the day. Avoid deep fried foods, bakery products and refined sugars. Use of long acting form of Vitamin B 6,
vitamin E and evening primrose oil supplements on daily basis at least for next 3 months 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.
Dr. Purushottam Neurgaonkar.
