I've been charting my bbt since December 2011. Every month until this one (July) I have seen a temp rise on or around day 22. This month I saw a rise on day 14 and it has continued to stay over cover line since then. I am now on cycle day 22 and it's hovering around 98.5. I'm feeling a little bloated since the temp rise but my period isn't due for another 9 or 10 days. This seems strange and I'm confused. Could I be pregnant?
