CM went from EWCM to milky right before ovulation?

So the last three days I’ve had lots of EWCM and flashing smilies on my Clearblue Advanced.

Today I had another flashing smiley and the test lines on my cheap opk strips are getting darker so ovulation should be coming soon. But I just felt a gush (sorry if TMI) and went to the bathroom to check and it was like watery but cloudy white CM. It was slippery, not sticky at all, but definitely not stretchy either.

Should I be worried that the sperm won’t be able to get through this CM? I’m worried! Really wish it was still EWCM. 😕
