What you are doing sounds fine. While we like to typically program 3 weeks of building volume/load followed by a recovery week, life can get in the way. You can only do what you can do. In general more aerobic volume is always better than less but you also have to make this whole thing workable for you and your situation. If you don’t do that then you burn out or become exhausted or exasperated and quit.
As this is your first go around with structures training I recommend being conservative and consistent rathe than trying to knock it out of the park every now and then. That consistency will really pay off in the long run.
