Hey guys, I need your help.
I'm a pre-everything transguy from Brazil who is planning to get transition this year. I'm already scheduling my top surgery and I pretend to start T soon.
I took a lot of years to get the courage to make this decision, and I only posted here once.
Well, now I'm with a serious doubt: as a gay guy who was engaged in a relationship with a cis-guy, I started to take contraceptive pills since 2008. It's been a long time since I don't have sex at all, but I've never stopped to take pills. And no, I don't take them to stop menses, because I still got them for a week, I just take those pills because somehow I got used to it.
Back in time, I thought how much I disliked to take it, and how it decreased my libido and changed my emotional. I have oily skin and blackheads sometimes, but I never had serious acne issues.
Still, I'm a bit scared to stop this thing just because women complains about some side-effects, like headaches, problems with menses, emotional change and stuff, but, in other hand, I plan to take my first T-shot in one or two months because, if I have money, I will get hysterectomy at the same day of my top surgery.
tl;dr: Can I start T right after ending a cycle of estrogen pills, or or is recommended to stop it a time before starting T? And, if I stop those pills now (tomorrow is the day that is supposed to me to start another cycle...) after so many years taking it, what should I expect to feel?
Can some guys share some experiences with me?

Thanks in advance for any response.
