Took apple cider vinegar to relieve cold and flu, now nose is bleeding?

21 year old female, not currently on any medications and have no significant medical history. Caught a cold/flu before Christmas, and immediately after getting over it I caught another cold. It finally escalated into a sinus infection on Friday, and it’s now Monday. I wasn’t able to see a doctor over the weekend so I tried the home remedy of drinking an apple cider vinegar drink 3x a day, which has helped significantly and I feel almost 100% back to normal, no more pain or discomfort, except my nasal discharge is bright pink and seems to be bloody, is this normal after a sinus infection? Or do I need to see a doctor?
