Sore legs!

Naomi • I am 23 yrs old. My husband and I are expecting our first child and we are extremely excited!!!
Here lately I have been having aching and soreness in my legs, as if I worked them out all day for a week, and it sometimes is so bad it hurts for me to walk. I feel like I have constant shin splints and my legs feel like they just want to cramp up all the time. Does this happen to anyone else and if so what did you do to help ease it?
