I have to take my BBT at 5am since I usually work at 6.. some days I work later so I made 5am my set time since itโ€™s the earliest I would wake up. But this morning I fell asleep with the thermometer in my mouth!! Lol!!! Didnโ€™t get a temp for it! Lucky Iโ€™m on AF so it isnโ€™t crazy important, but still๐Ÿคฆ๐Ÿผโ€โ™€๏ธ๐Ÿคฆ๐Ÿผโ€โ™€๏ธ
