Welcome to HCM.
Since you have been pregnant before, it is proven that you and your partner are normal as far as conceiving is concerned and your ultrasound
study indicates that you are ovulating normally and as provided by you, your Husband's sperm count
is normal, so it should not be difficult to conceive. Take the drugs as suggested by your gynecologist and time your intercourse around 12th, 13th, 14th and 15th day of your menstruation
, to have a better chance of getting pregnant.
