Not really sure why.. Couple days ago the backs of my legs were killing like I'd ran a marathon or something!! I ended up putting it down to me changing the pillow between my legs at night, started using a really big thick one and it fell out a couple times so thought I must b clenching my legs together in night to hold it in! But yday evening tops of my legs started to ache and woke up today with arms and legs so so sore! Hope it's not a sign of me coming down with flu just before Xmas!! Fingers crossed it isn't!! Anyone else had this or is it totally not preg related? Xx
