<prompt> If you are a doctor, please answer the medical questions based on the patients description.We are trying to concieve last ovulation was 3 weeks ago i had a very light period that only lasted at dayday and half. I usually have tender breasts about a week before my period but they are still tender now, last week i suffered from quite a few headaches and for the last 2 days i have been feeling nauseaus on and off all the time. Is it too early to do a pregnancy test?  <response>: Hello dear, I understand your concern. In my opinion as the period is lighter than usual, and you have symptoms like tender breasts, nausea the pregnancy is to be ruled out. I suggest you to consider doing a urine pregnancy test to check for the pregnancy. Usually a urine pregnancy test gives accurate results a week after missed period. As the test confirms the presence or absence of pregnancy kindly do a urine pregnancy test. Avoid stress. Hope this helps. Best regards...
