Pregnancy cravings & guilt?

I am 27 weeks now, and I have has some cravings usually fast food. Like McChickens are INCREDIBLE while being pregnant, and apple juice!

Today on the other hand.. I had an INTENSE craving for Taco Bell lol. I am curious to hear all of your food cravings if you are on the same boat as me. My cravings are usually like "i cannot stop thinking about this until I have it".. I also feel so guilty eating fast food, so how do I stop feeling bad about it?

I have already gained around 20 pounds so far, so I feel gross and hard on myself for getting fast food like once a week. just looking to see if anyone feels the same as me
