BBT chart - did I ovulate?

Laura • Pregnant with my rainbow 👶

Hi, I’m recovering from a complete molar pregnancy with coexisting twin. I finished chemo in october as my hcg continued to rise after d and c. I’ve been charting since October. I am going to try again in may but I’m just getting to know my cycle. This month I started Maca recommended by my gynae. She did a scan on cd12 and said my endometrium was 9mm thick and I might have already ovulated but she couldn’t confirm it. I also had a positive ovulation test the evening before. Usually I’ve been ovulating cd15-17, before the molar it was usually on cd14. But my chart is not showing this, my temp hasn’t really risen yet? My temp went down a bit this morning but I didn’t sleep well last night. Can anyone advise me? Have I ovulated?
