Super early sickness?

[Locket211]

So since 3dpo I've been feeling nauseous, headache/pressure, and all round off. Also have a kind of guy feeling that something is happening in my tummy. Am i being crazy or could this be ridiculously early symptoms?
Maybe i implanted really quickly or something, or is it just all the vitamins and Myo-Inositol I'm taking?
Did the deed on 27th august (negative test on 6th sep don't think it was this one). Then again 1st & 3rd sep and supposedly ovulated on the 2nd sep, so today (7th) I'm only 5dpo. What on earth is going on with me 😭

I've had one sided cramping every single day since I've ovulated (cramps are more central now) and other symptoms too, so who knows, maybe super early symptoms are a thing? I'm only 9 DPO today so I'll probably test on the weekend and if it's a BFP, then it might mean something is happening even after a short time from ovulation. Fingers crossed for you!
