Well my first appointment with a midwife, they couldn't get my blood pressure for ages, they tried twice, nothing, then did everything else, weighed me, tried to take blood (which was also a disaster, couldn't get any) and so by the time they tried again my bp was 144/100! I couldn't believe it as when I took it at home in the morning it was 135/82 or something!! She just said it was because I was so anxious with all the testing that was going on!
Took it the other day and it was 128 / 78 or something like that - so much better. I know it's high rather than low so maybe not as much help but thought I'd share my story - I really hope the bp sorts itself out! x
