You should worry about infertility
at least one year after regular effort. Krimson-35 contains an anti-androgenic drug and estrogen
. You can wait for some more time for natural conception to occur and then get investigated. The array of tests include assessment of hormones, abnormalities of genital organs, response of the uterus
to hormones and male factor evaluation. Then only you can be advised treatment. I do not think you have an incurable problem, but I advice you not to be hasty in taking medicines as unnecessary use of drugs without proper diagnosis does more harm in treatment of infertility. So, consult an infertility specialist and get advice. Take care.
