22 days after missed period heavy bleeding w/ cramps was my period or bleeding in pregnancy? negative hpt 21 and 30 days after sex

Probably not preg.: 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 happened) or 1 week after missing a period. Two negative pregnancy tests, done 3 or more weeks after sex, make pregnancy very unlikely.
