I am due to start my period tomorrow. Today I took one of the walmart $.88 pregnancy test which say you can take it the day after a missed period, but I thought maybe I would get at least a faint positive if I were in fact pregnant, but it was negative. Soooo.... my question is, I have taken my temps both orally and vaginally. My oral temp is in my normal range of around 97.2 and my vaginal temp is ready 99.3 and today climbed to 99.7. Which one is the most accurate? Could that test have been wrong meaning there just isnt enough of the hormone yet to show up? Im just curious. Mostly as to why my vaginal temp would be so consistantly higher than my oral temp.
