Getting mixed opinions on o day- help!

Ok so I thought I ovulated cd15. I usually use Ovia and Premom, FF is completely different than those.

Attached is my chart (going to use Premom vs FF). CD14 got my peak OPK on clearblue digital after 2 d

ays of high results, CD15 got my pregmate LH surge (same day as the temp dip)

On 6DPO (or what I believe to be if I ovulated CD15) had light spotting and a slight temp dip (implantation?)

Since then I've been congested when I wake up, on and off headaches, random cramps (yesterday had SHARP pings), on and off constipation (very odd for me), bloating, some random dizziness going up stairs and overall fatigue. The last time I was pregnant it was pretty much only those. No bb tenderness until 3 days after my missed period, no nausea.

So far all pregmates have been stark white, but the last time I got a faint 12dpo with clearblue and definite clear 2 days later, so not freaking out yet!

I will say, my problem with temping is I work a rotating day/ night schedule so my days off after working nights the temp can be unpredictable.

For reference: cd8-13 nights I worked, was off cd14&15, worked day shift cd16-19, off cd20-23 and this is now night 3 of 4 currently, night shift this week cd24-27

Last month was clockwork in terms of phase lengths. Period was 4 days, peak clearblue cd14, cycle was 27 days total

Had someone on another thread say o was cd21/22. FF says cd17. Everything else says cd15.
