Hi welcome to Healthcare magic forum. You are 21 years old and got married last year only. More over you are a P.C.O.D patient. So don't get tense about conceiving. Mental tension is one thing that promotes
infertility besides other factors. More over there is no ovulation so it may take time for your desire to come true.
Anaemia is also one of the causes of
irregular periods, and infertility.
Regarding
yasmin tablets , they are birth controle pills, but they will also help for treating P.C.O.D by suppressing the cysts. So you can use the pills with out any doubt.
Besides i advise you some non medical procedures as Diversion procedures
yoga,
meditation, reading books, hearing music, and if interested gardening.
Take more of green leafy vegetables, pulses, sprouts, egg, milk, meat etc to improve blood, and general health necessory for all deeds.
Wishing for a fruit ful recovery and thanks for calling.
