Headaches and light headed

Angela • I am 34 and have 3 beautiful children and my 4th is on the way!! I was scared at first but getting excited!!
Hey moms! I'm 17 weeks and I've been getting a lot of headaches and light headed if I stand for to long. Which sucks cuz my job is standing all day. Has anyone else ever experienced this? I don't just get light headed I feel like outter body experience. Arms and legs go numb and get heavy.
