Af or pregnancy?

Lizet 🌷

At 4 dpo I had light spotting I didnt think anything of it and at 10 dpo I started testing and it was a bfn. Between 9-11 dpo I had very sore nipples which have since subsided. At 13 dpo I had very creamy/whitish cm. Today (sorry for the tmi) my S/O and I did the deed and when I went to the restroom and wiped I saw light pink on the tp. I thought af was just heading her way but nothing since then. Btw sex wasn't even rough so 🤷‍♀️. I tested at 12 dpo and bfn and I haven't tested since then.I have always been regular and have never been a day late so not too sure. Have any of you had this experience?
