Hi Dr,i have to take fertab 50 for the first time soon,before doing an insemination,i already have one kid ,6 years old.Is there possibilities of twins with fertab 50 from the first treatment?i am 33 years old,168cms and 59 kgs,first pregnancy was so easy but this time it is not.all medical exams were good,but no pregnancy yet so my doc suggested fertab 50 coz maybe the ovulation is weak and simple insemination coz the spermes may are not living too much in the matural way,thank you for your kind answer.
