Of course you can adopt. But there is nothing in your charts to show a complete denial. In your chart, Jupiter is the lord of a Dagdha (burnt) rasi and hence is not giving its full results. Otherwise, in the natural course you can get a child even by the second half or end of next year.
In your husband’s chart, a Pitru dosha exists due to the presence of Rahu and Sun in the same house. This has to be remedied by visiting Gokarna in Karnataka, Tryambakeshwar in Nashik or Rameshwaram in Tamilnadu. I do not know where such facility exists in North India. You can find out locally. If this is remedied and Jupiter is energised (because of his being a Dagdha lord) by offering a Jalabhishek to Shivling on Mondays with proper prayers, you can have a normal child also.
