Hi, my last period happened Oct 28 for 5 days. Till then i did not get period, I thought I was preganant and had HCG testing after 20 days of my period delay. It was negative, and doctor prescribed Duoluton L and Karecon DSR(please make sure the spelling of this tablet) for 5 days morning and night to regularise my period.Will it work? One week over on completing my dose, still i did not get my periods. Will this affect if i get pregant??
