Woke up with pain

Ok guys I woke up with pain in my calf like super painful it hurts to apply pressure on my leg I have to walk with a limp it makes it worse that I did absolutely nothing at all to hurt it nor pull a muscle so I’m so confused I woke up stood up out of bed and was instantly in pain from me applying pressure to walk I’m still in pain I tried massaging it and also taking a shower neither helped with the pain . I’m currently still in pain every time I walk or even move my leg I’m 30w6d pregnant should I get it looked at?
