My periods are pretty regular they start quite heavy last 5-7 days, this month it was 4 days late and never really started it was very light barely anything on a sanitary pad it was mostly when I wiped and it stopped after 3 days. I've had none of the usual pmt symptoms however since the bleeding has stopped I've had some mild cramping and pulling sensations in my stomach and lower abdomen and a niggly lower backache. I've had a bleed so I'm not pregnant but should worry about the odd symptoms
