Advice??

Hi everyone so on June 24th I took a Plan B ( I never had vaginal sex but I just took the pill just to be safe) and I read the pamphlet I knew the symptoms so I knew what I was getting myself into before. That being said this past week I start my period and I knew that a period can be delayed due to Plan B but I’ve been having symptoms all week I’ve been kind of freaking me out. I’ve been having symptoms like nausea headache bloating and I always feel kind of sick after eating. I’m seven days late as of right now and I’ve taken two Pregnancy test since missing my period and I’m gonna take another one today but my pregnancy test both came up negative. I don’t know what to do and I’ve been thinking about drinking ginger tea just to see if that could help. Please don’t be rude in the comments I’m just super stressed I need an ease of mind
