Hi hun - going to bed now but didn't want to read and run -
Dizziness is a very common problem in pregnancy due to higher blood volume, the heart working harder and lower blood pressure.
I had this problem for a few weeks a short time ago - would be dizzy on standing and sitting and sometimes when sitting still, and felt weak and tired all the time.
The doctor told me to take iron - and I do have low blood pressure at the moment which explained some of it.
I started taking Spatone - which is iron rich water, you can mix it with orange juice in the morning.(doesn't constipate you taken this way either) I haven't had a dizzy moment since and I feel great.
However - ask your doctor before you start taking iron just in case this is blood pressure related.
