It is completely safe to have a hysterosalpingogram (X-Ray of the uterus and tubes using a contrast dye) in the first ten days of the menstrual cycle. The day the period starts is counted as the first day of the cycle. It is, therefore, completely safe for the baby to have been conceived this month itself. Since the tubes get washed out during the X-Ray procedure, there is a better chance of conceiving this month. You must try to conceive this month.
