This is really risky to be without medication for so long when you are taking regular medication for BP. Although there is no rebound hypertension
in cases od Telmisartin using, but it is not good for controlling your BP.
It also depends on the level of BP you are suffering from, if you are in moderate to severe range that is your BP is 160-180 systolic than it can be very dengerous and you have to do something for this and even if you are in mild BP range I would suggest you to do something to arrange for this problem and improve your condition.
Thanks and take care.
