Is this a good sign of conception?

I’m just going to list what I’ve been feeling since about 3-4 dpo .

Light headed/dizziness - ( Walking up the stairs requires me to lay down for a bit)

Nausea/vomiting - I can drink but Saturday I only drank a little and it was a puke fest

Little to no appetite - unless it’s a turkey and cheese sandwich or a plain mcdouble

Dull cramps - feels like I have to go #2 on and off

Cold/flu like symptoms- I went to the doctor but everything came back clear

Discharge - I was having milky discharge but now my period is 4 days away and this showed up when I went to use the bathroom a minute ago

I know I need to test but I’m waiting it out and I’m not able to see my obgyn until the 6th! I tried my best not to symptom spot but do these sound like symptoms of conception?
