I am trying to find justification for testing tomorrow

I had major O pains on CD 27 and even had a nice amount of EWCM so I am wondering if that is when I Oed and I had a delayed temp rise. Does this happen to anyone? On my current ovulation date (CD 29) I didn't have strong O pains but I did get this weird heavily bloated feeling that lasted about 5 minutes and maybe a tiny amount of EWCM. What do you think?
