My periods are usually always regular but last month I was a week late then when I was on I just had light bleeding lasting 2 days and was on and off for the 2 days...Then this month I was a week early for my period which was once again lighter than normal and only lasted a day and a half. Usually I am always on time every month and periods are really heavy lasting 5 days. I also experience really bad cramp and sore boobs before I'm due to have a period and for my first day cramp is usually unreal. For the last two periods i've had i havent experienced any cramp what so ever! I also read before that coldsores are common during pregnancy and I have recently just gotten rid of one and I'm constantly tired ... help pleaseeeee :-(
