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 per your history, you had history of 2 accidental unprotected sex acts I m the concerned cycle. And it was around the day of ovulation. So you are right in suspecting the pregnancy. 3 ) As you might be aware that the very first and important sign of pregnancy is a missing period. 4 ) If you have crossed your expected date of the cycle, then I will suggest you to get morning s first sample of urine tested for pregnancy. In case of doubt blood beta HCG test and USG will be of help. 5 ) Your all the symptoms can be related to pregnancy only if there is confirmed diagnosis of pregnancy as discussed above 6 ) Even if you are pregnant, you can opt for termination of the pregnancy with medicines safely till 9 weeks of pregnancy under medical supervision. 7 ) If you are not pregnant,then your symptoms can be due to PMS - premenstrual syndrome. In that case I will suggest you to opt for a healthy diet and regular exercise regimen. Start with long acting form of Vitamin B 6, vitamin E and evening primrose oil supplements on daily basis at least for next 3 months. I hope this answer helps you. Thanks. Dr. Purushottam Neurgaonkar.
