11 weeks and feeling worse not better!!

I'm now 11 weeks pregnant and started feeling ill at 5 weeks. I was hoping I was gonna start feeling better as I was coming out of the first trimester but I seem to be worse! Today I have an awful headache and I'm so nauseous! I get some days where I feel ok but then some days I feel bloody awful! Iv had to give up work and seeing friends as I can't cope with it! 😩😩
