I just checked mine for you. Three times 140/70, 143/71, 136/70 a bit higher than usual. Normally being on cycle increases your RBC count, therefore raising your blood pressure. Excess water retention will raise it as well. 170/100 is really high, have you been consistently checking it? Any stress or other strenuous activity before your readings? It fluctuates quite a bit throughout the day, maybe try again in a couple of hours, might've been a bad reading
The high reading persisted over several days. I was measuring twice daily. After ceasing the LGD, it remained fairly high for about 3 days, but is now back down to 130/75 ,which is my regular reading.
I did not measure my BP immediately before beginning the cycle, which was a mistake.. so i can't say for sure if it was caused by the lgd.
I'm going to begin another cycle in a week or two, this time taking consistent readings both before and during the cycle to see for certain if the lgd is causing it to spike.
