Blood pressure slowly rising?

Just curious if anyone else has had this but been ok. Normally my blood pressure is on the lower side at my doctor appointments. But lately it’s been “perfect” or within a healthy range. For me, I’ve noticed it’s slowly getting higher. Because it’s still within range I haven’t voiced any concerns to my doctor because it’s still ok and not a worry. But because I usually have it on the lower end I just worry about it in the back of my mind. Has anyone here experienced this and had no worries the rest of the pregnancy? I’m 32 weeks now
