Is my cat pregnant?!

In September, I got a stray female cat from my friend who fount her. At first, she didn't eat much, but then all of a sudden, she started eating more than usual. Instead of being calm and loving, she's become restless and playful. She's constantly running through the house. After 15-20 minutes of playing though, she seemed to calm down. After seeing her slightly round belly, I thought maybe she was pregnant, but that doesn't seem to be the case. Her belly isn't large enough to fit but only one or two kittens at the least! Also, even though her nipples are a darkish pink, they're small. But aren't regular nipples a polish color? I don't know... Also, she's actually letting me touch her tummy. She usually hates that! I also caught her sleeping in her little box a couple of times if that helps diagnose anything? And by the way, her belly is a mixture of squishy and hard. She's beginning to also lick around her nipples and lower belly. And her belly twitches in her sleep. Sometimes so much that it worries me... She is an outside cat, and there are a couple male cats on my street, but I don't see how they could get to her when were in the middle of a couple acres of land, and we have two grown dogs. Let's just say they don't like strangers. I saw an orange cat once in our ditch in October, but it never went into the yard. Can you please tell me what's going on or if my cats is pregos?!

Here's a picture

If you have an outdoor cat that is not spayed, she is almost definitely pregnant. Can you please bring her inside and keep her inside until the kittens have been weaned? Do you plan to spay her after this litter?

She's a cutie, but she probably is pregnant. You would not believe how sneaky a female cat can be while in heat.

Yes I do on plan on spraying her. Her and my other cat that we fount near the MS bridge.
