My period is Late

I usually get my period like every other week but now the 4th will be a month since the beginning of my last period. We’ve been trying to get pregnant so idk if I should be excited or not get too hopeful because maybe my period is just regulating and it’s going to come in two days🙃

Idk I’ll update if anything happens! What do you guys think I should do? Just wait for it to come or should I test?

*UPDATE*

It’s now the 4th and still no sign of my period. I have lower back pain and mild cramps and I’m emotional. All the symptoms of my period but no period. I can’t test until next Thursday because I’m at a school called job corps and we have limited store runs🙄
