Can I test your brains a bit more? AF is due on Wednesday (well, Tues-Thurs, not sure exactly which day she'll show!), and my bbt has been steadily rising for the last three days so it's now higher than at ovulation. I thought it should be staying roughly constant or coming down? Really confused as to what's going on
