I have a Harpactira pulchripes with a huge abdomen and I haven't found poop in her enclosure for a while. I thought at first maybe a dud egg sack but no. How could. I've sure this is her problem? How could I help her?

Not finding poops does not mean it's impacted.

Check if there is anything around the spinnerets.
Ok if said be the case should I continue to feed her regularly or maybe less? I've always fed her small prey item twice a week. Since she got really big I've skipped feeding her that much. I'm not sure this pic uploaded the first time. Take a look how big she is.

I've never dealt with impaction personally, but from what I've read, just having a large abdomen is not an indicator by itself. If the spider is acting abnormally - listless, scratching at it's rear end incessantly, dragging it's rear end across the substrate, drinking copious amounts of water, etc. - and that behavior is accompanied by an asymmetrical swelling of the abdomen (meaning a lump on one side or the other), then you may have a case of impaction. If you don't see any of the behavioral indicators, then it is very likely just a case of a fat T or one that is preparing to molt.

Do not feed in a while, it's quite plump. Simply make sure that it has an easy access to a drink.

If you feel that a molt is close (laying a mat (here difficult xD) the chellicerae are more protruded than usual etc) keep a corner slightly moist to help in the molting process.

A large abdomen is not always an indicator of impaction. It seems like an overfed spdier to me as tarantulas have very slow metabolisms.

I have dealt with impaction, the only way I confirmed it was impaction was by inspecting the "anus" of the tarantula, and finding a hard crusty substance stuck to it. She survived and molted fine, so Im led to believe it was a partial blockage, but I really couldn't tell a difference in her behavior that alluded to her being impacted. Chances are though your T is just in premolt.

not only is it not always an indicator, its almost never an indicator. With all the hype around impaction, many are led to believe its a common occurrence, its not, in fact, its extremely rare. As mentioned, crust around the anus would be the best indicator, but even then, seeing a crusty butt isn't always an impaction indicator either, just the most common for this uncommon occurrence.

Your spider is very fat and possibly in premolt. Impaction is actually really uncommon. I had it happen once when a piece of a previous molt was obstructing the spider's anus. And this spider was acting sick for a long time and had dried feces caked around its anus. If your spider is behaving normally then I wouldn't worry. Most likely overfed and in premolt.
