Hello I had an intercourse on 8 th August with my partner and 10 August I took 72 hours levenogestral pill with the advice of doctor .. and 17 to 20 I had a spotting and bleeding which is in between my periods cycle . After that 28th august (actually period coming date) I had my periods .. and it is also spotting and lightly so I consulted with a doctor and they ask me to take Beta hcg test .. nd test was negative non pregnant ... So she prescribed "crina Ncr 15 mg tablet for 5 days... And the course is over when will I get my periods? And which test is accurate? Bhcg test or scan or urine test??
