Trying to keep hope alive

My fiancé has irregular periods and we took a ovulation test around the time I was supposed to be ovulating. But I wasn’t and she was so we did a home insemination and she supposed to get her period around her birthday Halloween. But she haven’t got nothing but pregnant symptoms so I need some help we been trying on and off for two years. So she either gonna get her cycle this month or next month I hope she don’t get it because we keep having dreams about our unborn baby.
