I have been experiencing lower abdominal pains and flutters, sore enlarged breasts, nausea,acid reflux, sore ankles and mostly extreme tiredness. Hpt say negative whatever time of day but I feel pregnant. I have pcos and endometriosis so irregular cycles but last period was short light and spotted a few days later! Any advice please?

See your doctor. You could have a hormone imbalance causing the pregnancy symptoms.
