Hi,

Just wondering if anyone knows why a triphasic chart often indicates pregnancy?

Is it because the amount of Progresterone producted after Ov increases even more if implantation occurs, and then temps go up even further than the post Ov rise?

My chart is displaying a clear rise after O (steady at 36.9 at the moment - see below), so am I now on the lookout for either a dip around 7DPO, or a further sustained rise in temps?
