For the effect you want to create, totally useless. Modern birth control pills have very balanced progesterone and oestrogen, just enough to alter the female menstrual cycle, without the the other physical problems that the hormones can produce.
You would suffer very serious and potentially fatal liver disease if you consumed large amounts of BCP; with no positive effect. I realise there is literature in the CD community of forced BTC taking, it's a fantasy. When and if you go one HRT,in particular progesterone for GID the levels you are given are hundreds of mgs higher than in the pill. That is why the effect needs to be monitored. As others have said, don't self medicate. Would you self irradiate for cancer?
