16dpiui... Test?

Jul • 👶🏼 👶🏼💙💙

I thought my period was coming for sure I had already accepted I’m out this cycle! I didn’t take a test on Mother’s Day but instead have just been waiting for AF... it’s now 16dpiui... and I feel great today (yesterday I had period cramps and a tiny bit of spotting). I feel like I should go home on my lunch break and take a test. Do you think it will be accurate if it’s not first morning urine??

Thank you!
