Hi. My Soon-to-be-husband And I Had And Intercourse Last Dec

Hi. My soon-to-be-husband and I had and intercourse last Dec 4, 2015 at 3am. Had sex again on Dec 7 and took 4 tablets of nordette on Dec 11 and took another 4 tablets after 12 hrs. I had my first day of period on Dec 24 in the morning and we had sex again on Dec 25 even if i had my period bec we barely see each other. He's a seafarer and very active when it comes to sex. Today is Dec 26 and i am planning to take nordette again. Is it safe?
