ADVICE?!?!?

I ovulated last week (Thursday or Friday to be exact) and ever since I have been really nauseous and have felt like I’ve had to throw up. I have insanely bad heartburn, and my nipples feel extremely sore (tmi I know). I know that it is probably too early for symptoms of pregnancy (I attached my cycle and chart below) but I need to know if anyone has any insight on what this may/ may not be. I know I’m not sick because this has been happening (the nauseousness) even before I ovulated and I have taken pregnancy tests and everything is negative. Any advice would be appreciated as I am at a loss at the moment 😔😔 thank you 🙏
