Hi, I took Norethisterone to delay my period, as I was getting married, I was already a couple of days late when I started taking the tablets. I have since stopped taking them, I ve got very tender nipples and had some mild cramping but no period and today is the 5th day after stopping, so I decided to do a digital pregnancy test, firstly the results said pregnant 3+ but then changed to an error, so I m confused and concerned that I may have been pregnant when I started taking the tablets. Could I actually be pregnant? I ve had fertility problems, and was told it was unlikely to happen but fell pregnant about 15 months ago but then miscarried at about 7-8 weeks, I am not a fertile woman and my period is usually very regular, any idea what is going on please?
