Hi and welcome,
I am sorry as I am not clear form your question if you want to get pregnant or want to know if
duphaston will act as a
contraceptive. So I have tried to answer it both ways.
Taking duphaston from day 5-14 of the cycle may not prevent
pregnancy. The regimen that you are taking is not related to
contraception and is not supposed to provide contraception.
It is a
progesterone analogue. The initial part of the menstrual cycle is dominated by
estrogen hormone and progesterone comes in the later part. so theoretically, duphaston may prevent or delay ovulation by altering the hormone levels but this is not a guarantee.
The cycles have become regular because of the drug. Ovarian cysts usually prevent ovulation, so regular cycles with duphaston does not necessarily mean that you may be ovulating.
This means that if you are taking this drug and have an ovarian cyst, it is impossible to comment upon ovulation and pregnancy.
The best way to know if you are ovulating with duphaston is by doing an ovulation study. If you desire contraception, it is advisable to use another method like condoms. If contraception is desired, Injectable depo progesterones like depo
provera will be useful in both cysts and preventing pregnancy. So please discuss this with your doctor in details and then decide.
Hope this was helpful.
Thanks for using HCM.
Feel free to ask any more questions that you may have.
