Early O?

My cycles are usually around 30-34 days. Last month, with temping, it appeared I O'd in my 20's cd's. Can't remember actual date. Now today is cd 10. And cd 8 cm was very lotiony and now cd 9-10 it's been very watery.  To me it seems like I may be ovulating within the next few days. Is it common to ovulate at different times a month? Last month was wack for me, and didnt get af til 7 days late, bfn of course. And of course I didn't start temping til yesterday thinking it was too early. Now I'm wishing I would have started temping earlier cause my temp jumped today. In case I did O, at least we BD yesterday lol. ​
