I'm not sure if this is a pregnant thing or not. Yesterday I was walking around a bit - we went to a swapmeet, so it's not like I was walking for ages, or anything, just around a carpark. By halfway around my legs felt like I had been running or doing some sort of strenuous exercise the day before. They've felt like that since... believe me, I haven't been doing anything really energetic, just the normal walking and housework, etc. The thing is, having aching thighs is a pre-menstrual symptom for me, so i wondered if perhaps this is an early labour thing?
