Congratulations Daisy, I'm almost 32 weeks.
Whilst your BP is a little low, I wouldn't say it's dangerously low. It's always better to have lower BP than higher, especially during pregnancy, where BP can get dangerously high and you could suffer from Pre Eclampsia and gestational Diabetes.
Optimal blood pressure is 120/80, but this can vary from person to person and age. Also if you exercise alot, this can lower BP too.
I too have BP on the lower side, mine is usually 100/65 or around that and the only problem I may experience from time to time, is dizziness if I stand up quickly from a sitting position or if I'm stooping or kneeling then get up.
