Symptoms? Reply Plz :)

Hey there, I had unprotected sex last sunday so 6 days ago now and that night I had these sharp jabbing pains in my stomach which were completely painful and I think that was me ovulating. So since that night, the first few days were fine but the last couple of days ive been feeling really fatigued (gone to bed really early both nights totally exhausted!), the sharp jabbing pains come back every now and again but usually not so painful but noticeable, I have had this gross taste in the back of my throat like im about to throw up but dont...And thats usually stronger late at night, and ive been having headaches aswell, they havent been very strong but definatly very noticeable and come on and off, some being more sharp than others especially last night, gwd was a killer, felt like my brain was rolling around inside my head!! And I also felt dizzy aswell, like really spaced out and weird, and ive also been really gasssy lately which is unusual for me, so what do you think? I wassnt sure if its too early to be feeling this way?
