Symptom checker??

Hoping someone can help. My period isn’t due for another 8 days and I feel like I’m maybe overthinking things and imagining symptoms but wondering if anyone can help. Ovulated about 2 weeks ago and had sex most days. For the last 5 days I have been absolutely ROASTING, I mean like hot flushes, burning up, sweaty and clammy which is sooo unlike me. I am normally always freezing and wrapped up in layers! Also yesterday and today all my body has been achy and I have also had kinda sore heads/toothache! It seems like maybe I am coming down with a bug and that’s what my husband is putting it down to but I feel well in myself, just feel “strange” anyone shed any light?
