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 then the fertile period of cycle is between day 10 to 20 of the cycle . If you have unprotected sex act in the fertile period, then You Stand chance to get pregnant. 3. You can simply wait for the expected date of the cycle , and if you happen to cross your dates, then please get morning s first sample of urine tested for pregnancy. In case of doubt blood beta HCG test and and USG will be of help. 4. If you are already past your cycles date and your repeated pregnancy tests are negative, 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. Include more portions of fruits, salads and vegetables in daily diet. 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. You can use simple analgesic like paracetamol as needed to control the pain. Please seek prescription support from your treating doctor for getting the supplements and analgesic I hope this answer helps you. Thanks. Dr. Purushottam Neurgaonkar.
