4 dpo?

I'm 4dpo today and feel like I'm having some symptoms even though I no its to early. ..I have sharp side pain in my left side woke up nauseous and feeling very warm today! Yesterday at 3dpo sharp pain in left side and extremely tired..I read that if u r pregnant before hcg rises progesterone rises which can make u feel symptoms is that true? Did any of u feel shitty at 3 and 4 dpo? I'm trying not to symptom spot!!!! But going nuts!!!!
