Hi, I'm 13 weeks expecting twins, suffering with low blood pressure, going dizzy and feeling faint. Is there anything that can help?

Hydration. You should try to take in a lot of fluids, it could also be related to low blood sugar, and eating should help. You should see your doctor to make sure that there is no other cause for these problems.
Yes . Compression stalkings can be helpful for syncopal symptoms which you are describing.
