The benefits of BP meds could outweigh any risks of high blood pressure. I know that I will have to take BP meds when im pregnant. You should really consult your physician to see if this applies in your case. Aldomet is a BP med that is considered safe in pregnancy. I was on BP meds when I miscarried but had nothing to do with it. BP can be a serious problem in pregnancy and should not be ignored.
Other than rest like ur doing u can try BP medicine if ur doctor thinks it's necessary and avoid eating salt in all ur food hope u can get ur BP under control
