In pain, cant sleep, headaches

This may sound weird or normal I dont know I never experienced it in my first pregnancy. Since 10 weeks I'm 14 now my right leg has been having pain when I go to sleep cant sleep because of it. Itll swell but when I get up it sometimes goes away. Then it started for both legs. I prop them up because hey that's how you get swelling to go away no they gotten worse. I've been checked for blood clots (none). So now a new symptom a major stabbing headache that comes in goes in one spot but it only happens on the right side, where the swelling started on the first leg. I just wanna know has anyone experience this?.
