hi CB
This is my chart for when i used spi 5-9

As you can see my temps dropped and leveled a bit when taking the spi .When taking clomid they usually rise.But then i can't even say that for this month cos they've been up and down a bit like one of them heart rate monitors.
If its up still tomorrow i'd just put it down to the spi.It should drop when you've finished it.
