OK, sticking to the point:
There is no general consensus on the fact that taking estrogen in any shape will lower your testosterone.

Since PM contains miroestrol, that mimics oestrogen, there is no proof that just by taking it you will lower your T.
You touched down on BO, saying that it was supposed to have a "6-month time span and then your testosterone is supposedly lowered for good". On this forum, a lot of people have debunked this. Estrogen is stored in fat in the cells. The estrogen in BO seems to bind with fat more effectively, so it stores in your body and it has a longer effect when you stop. It's like continuing taking pills for some time after stopping BO, but, again, this has no effect on T.
Some users reported, and this is unproven, that taking PM sometimes causes T to rise, maybe to counteract the added E.
