Blood pressure going up, when medication should be taking it down, isn't unusual in my opinion. When I was due to have an op, my BP was around 150/90, so I was given Amlodipine to lower it. A few hours after taking the first dose, I checked my blood pressure, hoping that it might have gone down. It was 230/107!
130-something, over 76-ish, doesn't seem too worrying to me. The systolic figure is only slightly elevated, while the diastolic one is normal. I've just checked my own blood pressure and, after initially being told that I'm dead ("No pulse detected"), I see that it's 144/76 (which is consistent with my other recent readings). While I'll probably mention it to my GP at some time, I not exactly panicking over it. The consensus of opinion seems to be that a slightly elevated systolic reading probably isn't much to worry about if the diastolic one stays around where it should be.
