Late period

Hello I’m new here! I have some questions that need answering if possible! I usually get my period the same time every month. If I’m late it’s maybe like 2/3 days but usually no longer. Well I’m now 8 days late.. before my expected period I was having ALOT of pregnancy signs and symptoms. I took a pregnancy test and it looked like a faint positive (pictures below) so I took several more and got negatives. I got to where I could barely eat because of the nauseous feeling I had. It was terrible. So with that being said. I’m now 8 days late and I am at a stand still on what to do.. obviously it’s not pregnancy right?? I was cramping but now I’m not anymore. Anything at all helps at this point!
