Just need to vent a little!

So af is now 5 days late , for me that's really not normal because af for me is like clockwork, two negative tests, symptoms are slight cramps , very tired! , my nipples feel pretty sensitive I'm moody and just feeling off. Today is my birthday and I was so hoping this was it but my tests keep coming up negative and I'm confused 😔 just wanted to get that out of my head, if anyone has any thoughts feel free I'm open! ❤
