What’s going on???

So I’m not sure where to post this but I ovulated on Jan 30 and on feb 4 when I went to use the restroom when I wiped I had light pink blood and it went away and I would be 5 day dpo and had some cramps but nothing bad and on and off breast pain and today I’m 6 days dpo and now I am having some type of discharge. Could their be a chance of pregnancy?? I also woke up 5 days dpo with a sore throat and still have it today but not as bad.
