Third day positive opk

Laura • Mum to 2 👧🏼👧🏼1 miscarriage 🌈1 loss 🌷

Hello. I normally only ever get one positive opk, which for me is normally in the morning. And then it diminishes throughout the day and by the next morning it stark white negative. This morning is the third positive opk. Is there a chance I haven’t ovulated yet? My partner and I didn’t get chance to BD the last few days and would love it if we still had time. I don’t temp so I’m not sure
