My last physical activity was on 3rd october(protected) and my last period date was 18th September. Did multiple home pregnency tests which are all negative, did a UPT on 30th oct which was negative, then did a Beta HCG test on 2nd nov which was negative showed less then 1.2 hcg. So basically since my missed period it's been around  more than 15 days and still all tests are negative . My major concern is that can I be confirmed that it's negative for pregnency now. What can be the reason of my missed period then? One of my local doctor said it's normal  and to take meprate 10mg for 5 days. After these 5 days when can i expect my periods?
