Hi, I Went On My Honeymoon For 2 Weeks And

Hi, I went on my honeymoon for 2 weeks and took nnorethisterone to delay my period, before this me and my partner had not been using contraception as we are ready to start a family, I only needed to take 1 tablet a day to stop my period instead of 3, when I stopped taking them I have only have brown blood and not a normal full period, could this mean I am pregnant?
