Strange feeling week

not sure if its the weather, eating habits this week or something real. my temps are holding above my cover line but I've had about ZERO energy ALL week, taking naps AND sleeping in later than usual. time seems to be moving sooo slowly. Today I felt shortness of breath and bad nausea this morning before laying back down in bed. one app says AF due today and glow says not until Tuesday. No signs of the wicked witch yet. Haven't tested since Thursday when I got a BFN. too scared too see another one
