IS IT POSSIBLE???

I thought i was pregnant around Christmas but then bled for a whole week and was so disappointed. SO came in me on the 11th, 12th, 3 times on the 13th and glow says my fertile window started yesterday on the 14th but i know their predictions for me are never very accurate. do you think it could happen though? I was so disappointed not to be pregnant and im hoping this time it will happen for me. ill keep baby dusting this week but im just curious if maybe it could have happened already
