Not a good idea. I did this for 10 years. It took me 1 year just to STOP taking them in the runup to transition because the body becomes literally addicted to the estrogen level in them. Just try stopping cold turkey if you've been taking them long term every day. It is agony. Note: on par with heroin withdrawal migraines.
Doctors will always say it is 'safe' to take birth control pills but every single doctor I have ever spoken to has said that you should be taking a break for a period. If you ask a doctor is it all right to take a pill non-stop permanently so you don't have a period I'm fairly sure if worded that way they would say no, and that is not how the BPs should be used. One off overuse is fine, but long term every month overuse will begin to feminize your body shape even more and mean it'll be painful to stop taking them. If you take BPs in such a way as to prevent periods altogether you aren't taking them as prescribed, so you can only expect problems.
If you are expecting to transition and use testosterone ask for Norethisterone for short term use. Even this they will advise you to take a break from for a period because it isn't supposed to be taken to "stop periods". Just to lessen their severity for one reason, among others. It also is not a contraceptive, if that is a concern.
