Need help-please respond

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
I just started tracking my BBT and I had a spike today as seen below. I'm only 3 DPO, does this mean anything? I'm not too familiar with the BBT tracking so I'm curious if this temp spike keeps up, does that mean I might get my BFP In a week?!?! I'm kind of excited and nervous to know what it means!
