Should I test or or not?

Ok ladies so I typically have very regular cycles. I should have started my period today according to my basic period tracker. I used OPKs for the first time this month and I ovulated on day 19 of my cycle much later than Glow predicted. When I updated ovulation day Glow then pushed my period back about 4 days. This makes this cycle be 33 days which is much longer than my normal. I tested yesterday morning and got a BFN. I am only 10 DPO today but theoretically missed my period today. I have had an upset stomach and early morning/ late evening nausea. I also get very shaky and faint feeling around bedtime. Should I test again or wait a few days?
