Hi so I’ve messed my period by 9 days but I’m still getting negative tests. I’ve used clear blue and first response tests testing every couple of days in the morning. I’ve had sore boobs for a week now. Mood swings and fatigue, constipation which I never get. My periods for the past 6 month have been bang on time but I have had a history of cysts or bulky ovaries that have made me skip periods before but never with the symptoms I’m experiencing. Has anyone ever experienced this or have any thoughts? Thanks xxxx
