9. Side Effects Associated with Methotrexate Treatment Nausea Vomiting Stomatitis Diarrhea Gastric distress Dizziness Severe neutropenia (rare) Reversible alopecia (rare) Pneumonitis

10. Treatment effects Increase in abdominal pain (occurs in up to two thirds of patients) Increase in Beta HCG levels during first 1-3 days of treatment Vaginal bleeding or spotting

11. Signs of treatment failure and tubal rupture Significantly worsening abdominal pain, regardless of change in hCG levels Hemodynamic instability Levels of hCG that do not decline by at least 15% between day 4 and day 7 post injection Increasing or plateauing hCG levels after the first week of treatment

18. 3/16 CC: cramping continues on and off but the bleed is more like a menstral period Pelvic exam shows menstral blood in the vagina but the cervix is slightly dilated, uterus and adenexa are tender but no masses felt Ultrasound shows thickened endometrium with no gestational sac as seen 2 weeks ago
