Dr S is right. There is nothing you can do about it now. It is now all about bees surviving the winter, however many there may be. If there is not enough you will find out in spring or perhaps later in the winter. The only thing you were likely to achieve with an inspection of the hive, as you have apparently done, is, as Dr S says, to lose wintering bees. Losing the most important bee is also a risk you should not be taking.
All inspections should be done to achieve a goal. Think why you inspected them as you did, what you needed to ascertain from the inspection (prior to carrying it out) and whether you achieved your aim (what could be done to rectify anything you found). When you have done that your answers will be 'don't really know', 'don't know' and 'achieved nothing'.
Now, I suggest you tuck them up ready for the winter and cross fingers and toes, if you think that would help them. With no empty frame space there is nothing you can do. I would think they they have almost 10 frames of stores (honey/sugar syrup/pollen) which should be enough under normal circumstances to provide adequate heating through the winter months and then at least enough to start brooding. I would suspect that your two frames of brood is less than that, as most newbies over-estimate the amount of brood in the hive.
Get some practice at gently hefting the hive through the winter, for experience next year.
Are you intending treating with oxalic acid around Christmas/early new year? Have you/will you have some fondant ready should they need feeding later in the winter? And the means to deliver it, of course, with insulation around/over it if fed above the crownboard.
Bees could be bringing in small amounts of stores right up to Christmas, or it could stop tomorrow - I hear they have snow on the eastern side of the USA today, so we may be getting some much cooler weather after the next few days. Depends on our wind direction, I daresay, but prevailing wind direction is from there... We'll just have to take what comes!
