Should i wait to take another pregnancy test i took one yesterday afternoon and it was negative. butt im having nausea and headaches and spotting ?

Maybe later: If symptoms are related to menses or pregnancy: home pregnancy tests are very accurate, but if done too early, a negative result may be due to testing too soon. A urine test gives a reliable result 3 weeks after sex (when conception might have happened) or 1 week after missing a period. A woman can repeat the test if she did the first test too early, such as less than 2 weeks after conception.
