It's it just me ...

I'm 11 weeks n 2 days pregnant this its my 5th pregnancy but I have had 2 miscarriages . The thing that's really getting to me and makes my day to day life really hard it's the fact I keep getting really bad headaches . Dizzy Ness. Light headed. Pins and needles . And the sickness it's horrible I can't get on with my day to day life as I feel like I'm going to faint if I stand up for to long . Please tell me I'm not the only one who feels like this and what can be done to help me as I'm getting to the point where I don't know what else to do doctors don't seen to care and tell me is Just the pregnancy but it can't be day I'm day out . Please help any advice it's really expect.
