Pregnancy symptoms do not show up before the missed menses. You can wait for 7 days after the expected date of menses to check for pregnancy, if you are not in a dire hurry. Otherwise, you can get a blood test for beta HCG done even 1 or 2 days before the expected date of menses to check for pregnancy. However, this blood test is expensive (about Rs 600- 700), and it is usually not advised unless we are treating the woman with assisted reproductive techniques (e.g. test tube baby), to help in fine-tuning of the drugs required. If the symptoms are bothersome, please consult a gynaecologist.
