Chart help please! Why the steady temps after O???

[HisKhaleesi]

Hello, I have had an unusually long cycle this month thanks to the lovely HSG, but thankfully I FINALLY ovulated. My question is I had the lovely climb on days 1-4. But since then my temps have been almost completely stable. This seems odd to me as i usually get many fluctuations post o...has anyone ever experienced this or have any idea what it means??

4 DPO- 98.64
5 DPO- 98.62
6 DPO- 98.63
7 DPO- 98.61
8 DPO- 98.57 (finally came down just a hair)

From what I have read steady temps mean steady hormones x which can only be a good thing
