Stray pregnant cat. experienced answers only please?

Asked: Stray pregnant cat. experienced answers only please?

I've seen this cat around a lot lately, she's got to be between 8-10weeks pregnant by now I caught her and brung her in about 2weeks ago. She's about 10months old I would guess. Small framed and young so I'm concerned for her pregnancy (I've also seen a dog nearly attack her once that's when I first started trying to catch her) I can feel at least 3 kittens, not really moving around much but I know they move less as she gets closer to due date. I also have 4 kittens from a previous stray who I just rehomed the kittens are 6 weeks old and leaving for new homes in the next few days (I'm keeping 2) but back to the pregnant cat (I'm calling her icis) 2days ago around 7pm est (36hours ago to be exact) I noticed a clear discharge around her vagina. She was breathing heavier and pacing from room to room so I begain watching her. At one point she started calling out and my other kittens came running. Icis layed down and started feeding them!!! I quickly seperated them and she started crying out as if I just stole HER kittens away? Now I have her in my bedroom which I didn't really want because I have a 1yr old deaf pitbull as well but he knows better than to attck one of my cats. Especially a pregnant one or baby. Anyway she sleeps by the door and the kittens in a pile on the other side. This morning I don't see the clear discharge any more and she's acting normal (besides wanting to feed 6week old kittens that don't belong to her)

Basically I guess my question is WHAT'S GOING ON HERE AND WHAT SHOULD I DO???
I don't have the money to take her to the vet until next week as this weeks pay had to go towards rent/bills/pet supplys etc.
Also I am pretty experience with animals and the birthing process. So I am expecting experienced answers only and thanks in advance to any helpful tips/info
