Thankyou for the info. I haven't felt dizzy or anything like that. My ob seemed to be more concerned with my iron levels? Does this play a part in the low BP? I have always had a BP on the lower side (100/60) and have a history of hypothyroidism and anaemia. I did a search and found an article that said the 3 can be related but I never know what to believe when found on the net.
