1) You want to relive every tragic event of your life every time somepony gets curious?
Sorry, I try not to live in the past if I can help it.
2) Well hold on now. Let’s see what you’ve got.
3) I believed they did when I was much younger. And their effect has been… Substantial. I’ve never had a estrous cycle that I’m aware of. Hormone imbalance is extremely dangerous, though. That’s why I still take them now, even though Boscov and I are genetically incompatible. If I stopped there’s a danger that my body might go into overdrive and be unable balance itself naturally. And then I’d still have to be on a drug, but a much more expensive one. Either way has certain dangers, but birth control is much cheaper.
Back to your question, I do not presently take birth control pills for birth control reasons.
