Hi Dr. Purushottam welcomes you to HCM virtual clinic. I have gone through your query. I think I have understood your concern, I will try to suggest you the best possible treatment options. 1)First of all do not panic. 2) If you have had unprotected sex act in the fertile period of your cycle, that means between day 10 to 20 of the cycle, then there are chances of you getting pregnant. 3) at first ,I will suggest getting morning s first sample tested for pregnancy. If the test results are doubtful, blood beta HCG test and USG will be of help. 4)Common symptoms of pregnancy are-- Giddiness Nausea Vomiting Loss of appetite Sleepiness Frequent urination Fatigue Heaviness in breast. You may have any of these symptoms 5) If you are trying to conceive, I will suggest to indulge in a healthy lifestyle, a healthy diet and regular exercise regime. Include more fruits,salads and vegetables in the diet. Avoid deep fried foods, bakery items and refined sugars. Also, start on Vitamin B 12, Folic acid and Omega 3 supplements.
