I am 49 I had the mirena removed June 19th got my period the 22nd. Started the pill on the 24th...took it faithfully everyday at the same time, except about the 5th day of starting it and then took it as soon as I remembered, I didn t get my period in July, started a new pack on the 23rd of July, took a pregnancy test on the 24th of July it was negative, could it be possible that I m pregnant?
