Hi there, I have understood your concern. I will suggest you the best possible treatment options. 1 ) First of all do not not panic. 2 ) The very first and important sign of pregnancy is a missing period. If you have history of regular cycles and also there is history of unprotected sex act, and if you have crossed your expected date of the cycle, then you stand chance to get pregnant. 3 ) In such case, 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. 4 ) If you have positive pregnancy test, then you can either continue with the pregnancy if you wish so, or else you can opt for termination of the pregnancy with medicines safely till 9 weeks of pregnancy under medical supervision. 5 ) If the pregnancy test results are negative, then you can simply wait for the onset of periods or induce the periods with Tab Regestrone. Your treating doctor can guide you further about the doses and withdrawal bleeding of the same. 6 ) Your jaw pain can be due to some tooth problem or ear infection or jaw joint swelling. I will suggest you to take Tab paracetamol as needed for the pain. I hope this answer helps you. Thanks. Dr. Purushottam Neurgaonkar.
