When do I test?

So this was my first time using opk’s. Based off the information from you lovely ladies I believe my surge was around 11/2. However Glow said I ovulated on 10/31 based off a picture of the opk I uploaded. Anyways, It changed my period date based off of that. I normally start between the 18th-20th. When would you take a test based off of these test. (The test that aren’t marked are the 4th and 5th)
