Hi, i had two days of spotting and then it stopped, took a pregnancy test a week later and it was negative. lots of tummy pain two weeks later and still no period.

Can call Dr on video: Home pregnancy tests are very accurate and not affected by foods, herbs, common illnesses, sexually transmitted diseases, or medications. A correctly done urine test gives a reliable result 3 weeks after sex (3 weeks after when conception might have been) or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon.
