I have had cysts previously they went away after thyroid meds due to hormones. I have been regular but I am now 2 weeks late and have every prego symptom. I took one neg test 2 days after period no more. Symptoms: Nausea, swollen breasts, back cramps, moody, crying for no reason, urinating often, hungry?? I called the doctor and they said they could call meds in so I would start but I don't have a good feeling about that. Could this still be cysts?
