I'm 21 weeks pregnant and whenever I've had my blood pressure recorded in my notes it's always been a bit low (90/60 ish). I haven't had it taken for a while but I've been feeling so off lately and wondered if it is maybe low blood pressure. Just feel really exhausted and as though my heart is weak and nausea has returned. I also get a yawning feeling in my body/chest.(I've had loads of tests on my heart before due to palpitations so I don't think it's this). Wondering what low blood pressure feels like to others who have it?
