If I had an LH surge yesterday morning , did I ovulate yesterday or Today?

Question

These are from the last 4 days. I am curious what anyone thinks if this was my peak or did I miss my peak at night maybe since I didn’t test on the 18th during the PM . I’m thinking I ovulated yesterday the 19th? 
I’ll list here in order from top to bottom when I took them 
1 - 16th am (11 am ) 
2 17th am ( 11-12pm)
3 18th am ( 11am ish) 
4 19 am (11am) 
5 19th (12pm ) Positive 
6 19th (4pm) Positive
7 19th (9pm) 
8 20th (11am) 
9 20th (3pm)

Answer

Ovulation occurs within 12-36 hours after your positive OPK. OPKs don't confirm ovulation. You had a surge. If you have sex before, during, and/or after the surge, you have a chance assuming you ovulated. You will need to chart BBT to confirm ovulation.

Answer

The two tests look like they were positive so one of them days you could have ovulated

Answer

I meant to say number 4&5 are the positives from the morning-noon yesterday the 19th.

Answer

You likely ovulate 12-48 hours after your first positive. It might be because they are dry, but none of those look positive.
