Lactation but not pregnant is it because i was on antipsychotics last year? also i briefly had an period that only lasted two days which was very light?

Yes, antipsychotic medication can cause nipple discharge because of increased prolactin level. You have period, even it was light, so you are not pregnant.

I understand your concern. Antipsychotics medications like Haldol and Risperdal may cause lactation. At age 27 light period can be due to Anxiety caused by stresses: •Relationships/ Marriage •Separation •Parenting •Finances •Work Please see a Psychiatrist for: • Diagnosis • Antipsychotic medications effects • Therapy for stresses in your life • Medication for Anxiety • Breathing Relaxation
