White/yellow/watery CM?

I had an LH surge 10 days ago and all signs pointed to ovulation. Then after that, my cervix descended and got firmer, CM dried up a good bit. But a few days later  (4-5 dpo) I had strange white CM (stretchy but not sticky) and the last 2+ days (7-9 dpo) I have copious amounts of watery discharge (I have to wear a liner/change undies) and now it's gone creamy white/yellow mixed with the water. Anyone else had a spike in CM amounts a week after o? Also my cervix has gone back up and softened again. I'm cramping lightly since 5 dpo and had VERY strong cramps on the right side on days 7-8 dpo. I'm confused if THIS is ovulation, pre-AF, or pregnancy?
