Helppppp

I’m 8 days late. I have the same symptoms every single time before i start my period and this time...none. It’s been a month since my last period. I took 2 tests 4 days ago and they were negative but still no period.. i woke up 2 days this last week nauseous but never puked and it was a nausea I’ve never experienced before! I have had bad migraines and honestly cannot stand my boyfriend when he has done nothing wrong... opinions?
