Hi my period is about 40 days late. june i had 2, one was about three days long. had spotting only when i wiped on aug 20. i saw a doctor yesterday urine sample said negative. wont hear about blood test till next week. could i be pregnant?

Maybe not: Today's pregnancy tests are very accurate and not affected by foods, herbs, common illnesses, sexually transmitted diseases, vaginal spotting, or medications. A test gives a reliable result 3 weeks after sex (3 weeks after when conception might have been) or by 1 week after missing a period. If done sooner, a negative result may be from testing too early such as less than 2 weeks after conception.

Unlikely: Conception occurs within day or so of the sex. It takes about 3 weeks for the embryo to make enough HCG for a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully
