Hi there, I have understood your concern. I will suggest you the best possible treatment options. 1 ) First of all do not panic. 2 ) All your symptoms can be related to pregnancy, if you have any positive definite indicator test for pregnancy. 3 ) As you might be aware that the very first and important sign of pregnancy is a missing period. If you have regular cycles, and you have crossed your dates, then please 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 your pregnancy test results are negative, then your symptoms can be due to PMS - premenstrual syndrome. Breast discomfort, headache and abdominal pain, mood changes are few of the symptoms in PMS . In that case I will suggest to 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. Please seek prescription support from your treating doctor for getting the same and analgesic like paracetamol for headache, I hope this answer helps you. Thanks. Dr. Purushottam Neurgaonkar.
