Suggest Medication To Help Conception

I had my period last week. Monday through monday. I always start a new month of sprintec on saturday after starting my period. My husband convinced me we should try to get pregnant a couple days later. So i took 1 pill saturday abd 1 sunday and then stopped taking them. Its friday and i started my period again. How long will it last? And when will have the best chance of getting pregnant after its over?
