This hurts

I don’t know why I even gave myself hope. My period had been 3 days late and I was so excited that this could finally be it. But nope just used the bathroom and there is my period.I just jumped from a 27 day cycle to now a 30 day cycle. My period are never late and always on time I haven’t been taken anything new or stressing . I hate my body for tricking me I’ve been doing everything right literally everyone around me is getting pregnant and here I am not knowing what’s wrong . I just give up I really do had this whole Christmas pregnancy revealed planned in my head I really hate this
