Weird symptoms!?

So according to glow im 3dpo but I think I ovulated earlier than that. On Sunday I had a pain in my left side and i usually have that when I ovulate. Well yesterday morning I woke up starving and im usually never hungry in the mornings. Well then I got really nauseous and it didnt go away until I ate something. And thats been happening from since then. Ive been constipated too and extremely gassy (tmi I know) but im usually never like that and I had all of those things happen when I was pregnant. Has anyone else experienced symptoms that early before? Or am I reading too much into it
