Managing Postpartum High Blood Pressure - #52177

I am a 2 year postpartum mom after i had my second baby. In third trimester my blood pressure became very high and eventually the baby had to be delivered with emergency c section. In my first pregnancy I had high blood pressure after normal deliver of the baby. This time I took medication for around 6 months after delivery and it had stopped. But with some bad news in the family, work stress, kids work etc. My blood pressure came back 4 months ago and I am taking amlodipine 7.5mg daily. My readings on left hand are generally 110-120/86-91. I feel the lower number still comes high. Upper number never come high anymore. I am in Canada and have 2 and 4 year old kids. The doctor here says even if just lower number is high it is still high blood pressure. He did all the blood work and everything was normal even kidney function. Little high cholesterol. I want to know why my lower number still comes high and what can be done from Ayurveda perspective. Someone suggested medha Vati. Can I take that. I know life is little stressful to manage here with kids and work. But I want the blood pressure to be okay. Please help.
