I’m 2 days late for my period. My period should of came last Friday and today is Sunday and still no period. I only felt lower back pain on Friday morning but no period yet. I took a pregnancy test yesterday and it was negative. Which I wish it was a positive 🙏 so I guess I’m not pregnant 😢 now I’m thinking maybe the Covid vaccine has to do with it?! Last month my period came 2 days late as well but I did feel my actual period cramps before and this month only lower pain for about 1 hour and it went away. Could the test be wrong? Or is it the Covid vaccine effects? I don’t want to get my hopes up either so idk what to think now.. has this happened to anybody else? I want to re test but I’m scared to get another negative and then my period will come like always. What should I do?.
