Had unprotected sex on 26 March . Took ipill. A week later had light but dark bleeding and along with clots for 6 days. Took a pregnancy test using appolo pregnancy test kit 3 days later it was negative . Took another test a week later with the same brand test kit and was negative. But periods are not coming. My period was supposed to be on 9th April . Is the test results accurate . Morning urine was not used as it said it was not necessary for this test kit.
