I've been feeling fluttering in my stomach for the past couple of weeks. It feels like the early movements of a foetus. But I'm pretty sure I'm not pregnant. I haven't had full sex for 3 years. Only manual stimulation in January (tmi, sorry). I've still been getting AF, although my cycles have gotten slightly longer (average is now 32 days, it was 28 before Christmas.) Also have slight backache today. Very strange. Anyone else had similar?
