You are 4 days late for your period and now im getting pink stuff when you wipe could it be implantation bleeding?

Implantation bleeding occurs when a fertilized egg implants into the lining of the uterus. It typically occurs 10-14 days after ovulation and lasts for 1-2 days. Implantation bleeding is usually light and may be accompanied by mild cramps. Pink spotting when wiping could be a sign of implantation bleeding, but it could also be a sign of other conditions, such as a sexually transmitted infection (STI), a hormonal imbalance, or a miscarriage. If you are experiencing pink spotting and you are concerned about the cause, it is important to see a doctor.
