hello doctor,i am 29 yrs maried for 1.5 yrs. I m trying to conceive since may 09. i conceived in sep 09 but doctor said it was chemical pregnancy(faint positive).Now, i am not able to conceive, doctor said it will take time. no problems with sperm,ovary and uterus. In mar 10 she prescribed letsi 2.5 mg from 2nd day for 4 days and duphaston 10 mg from 14th day. I want to know that can i conceive with this treatment as we want a baby. and is there a posibility that my tubes are blocked, as i had conceived once..M quite worried. thanks for ur answer.
