High blood pressure following stroke

After my stroke, I was told it could be bad to have my blood pressure get too low.

Thanks; that makes two of us!

This is just my spitballing here: A stroke can have many causes, and a result can always be poor muscle tone and/or control, but also visual and vestibular degradations that make standing and walking somewhat more dangerous than prior to the stroke. One problem with drugs that lower blood pressure is that they often have to be 'titrated' to the individual's system and their natural tolerance and reactions to ANY drug. In some instances, a first stab at a dose will still be too much, and instead of a next step being a boost of the dose, your prescriber finds you'll have to lower yours in order to not become dangerously hypotensive. For example, metoprolol is notorious for having people go into bradycardia, a HR less than 60 BPM. Even if one is fit and healthy, in some cases an HR less than about 50 might put them into a tailspin, especially if they have ventricular hypertrophy, or enlargement, where they don't pump an average amount of blood volume with each contraction of that vessel.
You are early yet, at only 6 weeks. As your system climbs down off the wall from all the stress and any tissue damage, your heart rate will probably slow some, maybe as much as 10 BPM on average. Your blood pressure will probably reduce somewhat as well commensurately. If you have too much trying to beat back the heart's contraction force and speed, you might find yourself in a bit of bother. So, slow and steady is the plan...for now.
