Did I miss my shot this month?

My predicted O-day isn’t until May 1st. But normally I’ll use opk for a few days prior. This is my first cycle after a miscarriage also so I’m unsure if my cycle length has changed. Normally my opk slowly get darker until they are positive. Yesterday’s opk was darker than today’s though. I had tested the day before yesterday also but didn’t log it under strips.
