What’s my body doing?

This month has been out of the ordinary for me or so I think, as I’m new to OPKs. About 2 weeks ago, I tested ‘High’ for about 7 days, never making it to ‘Peak’. My body was showing me signs that it was prime time. About a week later I decided to test again because I was seeing EW and I was ‘Peak’. Today I’m also seeing EW and am so confused and perplexed. Anyone think I could possibly be preggers? Today’s also the first real day that I’m starting to wondering as I was super tired and had no motivation.
