Is it normal for my thighs to ache in pregnancy?

Pain . Aches and pains are normal in pregnancy, you are living for two remember! take it easy do mild excercize, rest adequately hydrate sufficiently, and perhaps the most important thing is to decrease stress which is important for the baby inside you. Hope this helps.
Yes. Unfortunately, it is normal for everything to get achy in pregnancy. You can rest, use warm compresses and tylenol (acetaminophen) for muscle pains. Regular exercise and stretching can help prevent some pains- prenatal yoga is a nice combination of the two.
