Почему у меня темные кровяные выделения во время беременности?

Trying for a sibling and not getting pregnant immediately is completely normal. Two months isn't a long time, so there is no need to worry too much yet. To increase your chances, you should track your ovulation period, have sex during that time, stay healthy, and avoid stress. Additionally, the partner should be healthy as well. 

Radiation is neither dangerous nor harmful to an unborn baby when the mother's stomach is well covered during pregnancy and X-rays are taken. The child was probably well protected by the lead plate covered by the pelvic region during the X-ray. In general, radiation obtained from a single X-ray is so low that it cannot make an early pregnancy harmful. Nevertheless, telling the doctor about the X-ray and pregnancy is always the best choice. They might wish to examine the pregnancy more often to make sure that it is developing properly. 

The semen analysis report shows that there are some abnormalities in sperm count, motility and morphology. These effects might be responsible for the problems in fertility. It is advised to see a urologist or andrologist for further assessement and treatment. They can give suitable advice and treatment that may improve the odds for having a baby.

On average, the menstrual cycle lasts from 3 to 7 days. There are pregnancy possibilities even if having sex at any time, but the chances are greater during ovulation, which usually occurs on the 14th day of a normal cycle. If your period started 4 days ago and you have a 28-day cycle, ovulation could be in place now.
