Help! Please don't just look...

HI everyone, so me and my SO had sex every other day starting the day after my period ended and every day during my fertile window. Yesterday I went pee and when I wiped I had a looooong gooey string of super LIGHT yellowey color and was very gooey and sticky and pretty thick in consistency. A lot of it too. Currently 5 dpo and wanted some input on it?? Also, one day after my fertile window ended, I had a pretty bad pain on my right side-hip area. A supposed to come in 8 days.
