Last night walking home from my mum's house (all of about 500 yards!) my leg started aching, from the hip radiating to the knee. It wore off after about an hour or so. I slept no problem and it hasn't bothered me at all again until about 3.45pm this afternoon. Again, its an ache from the same knee to hip. Does the two episodes of pain being about 18hours apart sound DVT like? Or is that a constant pain? There's no obvious redness or swelling and I can walk flat footed. I'm hoping it's just the beginnings of normal third trimester leg cramps, but my pregnancy book and other threads on here have made alarm bells sound! I'm 30+6 by the way.
