High blood pressure...

Do any of you ladies know of certain ways to keep blood pressure down without medication... long story short my oldest (4) decided she was going to go in my bed room and take all the things off my night stand. She was upstairs in her room playing like normal so it never crossed my mind she would mess with anything. I was also cooking dinner and had her sister(1) with me. I ask her to come down to dinner to only discover she was covered in baby powder. First time for her to do anything like this... it gets better though... I go to her room and discover not only was it baby powder but also my prenatal vitamins, my antacids, my blood pressure medication, mixed altogether with water. Thankfully she did not ingest any of them. I’m 36 weeks called my doctor yet they said they couldn’t do anything to help me figure something out since my insurance won’t cover the medicine. So I’m at a loss they have already upped my meds twice last week and I would have ran out anyways cause they didn’t inform my insurance or pharmacy of the change. I’m worried for my baby since blood pressure is not something to mess with. Any suggestions would be greatly appreciated..
