Hi Cass Blob
By blood count I presume that your Dr means your HB. It is quite common to have a low HB during pregnancy, but I would not class it as normal. It would be a good idea to start taking an iron supplement This would help to increase your HB
For your low BP try taking things easy for a few days. When standing up do it slowly. Make sure that you are drinking at least 2 litres of fluid a day
