Dizzy

So I’m 12 DPO today and I woke up feeling like absolute garbage. I have a killer headache, insane nausea and I’m ridiculously dizzy. AF is suppose to come on Saturday and I’m trying sooo hard to wait until then to test. I usually get headaches before AF, in reality I get headaches all the time, but I never get dizzy like this. Debating if I should test today or keep waiting. I’ve been up for a couple hours now so I missed FMU. Not sure if it’s a waste to test later today or if I should wait until tomorrow. Thoughts? Does anyone get dizzy before AF makes an appearance?
