First month TTC and charting

Sarah • I`m 32 years old and TTC my first child. My S/O is 39 & has a 16yr old so we are trying for one of our own. Very excited
This is my first month TTC and I just got my BBT right before I ovulated but I'm 3 DPO and this morning had a high temp which isn't normal. I know I'm only 3 days post ovulation but can this be a sign to my BFP?!?! if I run high temps the next 7 days similar to this that's good right?
