Hello
Thank you for your query.
The possibility of
fertility / conception depends on many factors.
Firstly your ovulation has to be confirmed, since your IUI was done, i assume you ovulated properly.
your husband's
semen analysis has to be normal.
Your fallopian tubes have to be open, and the patency tested by HSG / preferably
laparoscopy.
Susten 400 is prescribed for luteal phase support after IUI in case you conceive.
IUI definitely raises the chances of
pregnancy, and has a success rate of 10 - 20 %, but its success can be lowered by your age, presence of fibroids etc.
yes, after IUI and using Susten, you do have chances of conception provided all the other factors are normal.
Take care.
And do not panic till you have / miss your next period.
