Sooooo

So my period was supposed to come Monday. I tested Wednesday morning got a neg. I’m now 5 days late. My stomach has been bloated since before I was supposed to start. I keep getting slight little cramps here and there, I’ve constantly had a headache that not even excedrin really took it away (excedrin always takes migraines or slight headaches away), today I woke up and a little while later got out of bed and I started to feel pretty dizzy. Should I test again today? Anybody else had something like this and then got a positive? I have slightly irregular periods so I’m not even sure but here lately they’ve been around the same time frame. Thank you in advance 💞
