Hello,
Thanks for the query,
Ideal size of the follicle at the time of ovulation for it to fertilize is 18-24mm.
Since the size of your follicle was 30mm at the time of rupture, there are less chances of conception or
pregnancy.
Duphaston and
susten are given to sustain pregnancy and to reduce the chances of
abortion in high risk pregnant women.
Hope this helps,
regards,
Dr Nilofer
