I had a miscarriage in may. ever since i've had extreme fatigue, pain, nausea, migraines, and mild depression. as well as long cycles. is this normal?

No, see doctor: The mild depression is understandable after any loss, but still needs to be addressed and treated with counseling and/or medication since it has been ongoing this long. All of the other symptoms are not normal after a miscarriage several months ago and need to be evaluated as well.

No: mOther than the mild depression (if it is because of the loss of the pregnancy) - those symptoms are not common, especially so long (5 months) after the miscarriage. (the heavy cycles can be normal, but best to see your doctor and have a sonogram and make sure nothing unusual with the lining of your uterus). The emotional stress of the loss may well contribute to the fatigue, migraines and other

Depression, Anxiety: I understand your distress. You have gone through emotional turmoil starting from relationship to pregnancy, and then miscarriage with feelings of sadness, hurt, upsetness, confusion and feeling bad. These intense feelings have led to anxiety with nausea and migraine; and depression with extreme fatigue. See Psychiatrist for Diagnosis, Therapy for stress, Medication, Breathing Relaxation, Yoga
