Trending down temps in LP? Newbie needing some advice

Hi there! This is my chart, I am new to charting and using the Apple Watch for temping. I have PCOS, irregular and have only just starting to have *actual* cycles recently. Wanted to get a jist of what was going on; will use bbt next cycle. Anyway, I believe I have ovulated. I am sore, cramping like CRAZY, especially yesterday and have sore boobs etc that all fall in line with TWW. I am just wanting to try and understand the dip in temps. Is this normal, or can it be normal? Or does this mean something? I know charts can tell you lots but equally nothing at the same time. Just a gal trying to navigate my first ever (near) full cycle of temping.

Thank you for any help 🤍
