Early pregnancy signs

Erin

So my fertile window just ended yesterday and today I am feeling so crummy I feel sick/nauseous, run down/achy and super fatigued so I was wondering to those who have conceived before is that what can typically happen a few days after ovulation if you’ve conceived? I know it’s way too early for me to test but I was just wondering should I or should I continue to wait? For several more days? Thanks in advance!
