I started my period last month on 11/3 and it lasted until 11/6. Glow predicted my period for December would be on 12/1. It is now 12/7 and no period. My right ovary seems to be cramping lightly every once in a while for 2 days now. My breasts are swollen and sore, but they are more sore on the sides under my armpits. I have been bloated and eating a lot more than usual (oops). Im not sure exactly how many days is normal for my cycle because I just started tracking it last month. Is a 35 day cycle normal? Should I test?
