Ethinyl estradiol as a last resort

Due to multiple issues with ordering estrogen I am close to running out and I am unsure when my new supply will arrive.

With that said, I am curious if ethinyl estradiol would be okay as a substitute for a short time. I understand the dangers associated with the substance but, even with those in mind, it is better to me to be on estrogen in some way rather than have testosterone. The longest I would likely have to be on it for is a week, factoring in how much I have left and the typical shipping times of the companies. If i have to be on it longer than a week then I am simply the most unlucky person when it comes to ordering estrogen and that fact already seems to be true with the myriad of issues I've already had.
