Two-Week Late Period with Light Spotting: Causes, Evaluation, and Next Steps

A period 2 weeks late with pink spotting on wiping has several possible causes. Pregnancy is the first consideration.

Differential Diagnosis

1. Pregnancy

• Implantation bleeding: Light pink/brown spotting 10–14 days post-ovulation; brief, scant.
• Early pregnancy loss: Bleeding may increase; hCG initially rises then falls.
• Ectopic pregnancy: Abdominal pain, shoulder tip pain, dizziness—emergency.

2. Hormonal / Ovulatory

• Anovulatory cycle (common with stress, weight change, PCOS, thyroid)
• Perimenopause (irregular cycles, vasomotor symptoms)
• Hormonal contraception changes (starting/stopping pill, IUD)

3. Medical Conditions

• Thyroid dysfunction (TSH)
• Prolactinoma (galactorrhea, amenorrhea)
• PCOS (oligomenorrhea, hirsutism, acne)

Recommended Steps

1. Urine pregnancy test (first morning urine). If positive → OB/GYN.
2. If negative and no period in 1 week, repeat test or get quantitative hCG.
3. Track bleeding pattern, associated symptoms.
4. Schedule clinician visit for history, exam, labs (TSH, prolactin, FSH, androgen panel if indicated), possibly pelvic ultrasound.

Treatment Depends on Cause

• PCOS: lifestyle, OCPs, metformin
• Thyroid: levothyroxine or antithyroid drugs
• Anovulation: progesterone withdrawal, ovulation induction if TTC
• Stress/weight: counseling, nutrition

When to Seek Urgent Care

Heavy bleeding (soaking pad/hr), severe pain, fever, syncope, shoulder pain → evaluate for ectopic or hemorrhage.
