AF due 3-6th Dec looking for a buddy

Lisa • I have a daughter who turned 4 in Nov 2015 I feel very lucky. I`d love a sibling for her, she`s also asking me for one x
So the last time I had boobs this sore I was pregnant. I've had major constipation for ages now. Otherwise I'm feeling pretty good.
Anyone else convincing themselves there's a chance or am I just setting myself up for a fall again??
