I'm 22 days into my cycle and my iphone P Tracker says i have a 23 day cycle. I've been so unwell for the last five days and I can't sleep at night but I'm always tired. I'm bloated beyond words and I've got cramps. I only EVER get cramps the day of. Don't get me started on this metallic taste and if anyone catches me burping I'll die of embarrassment! Would it be normal to have signs this early? Am I just run down, gassy and tired with PMT? x
