advice needed

I have a 4 year old female simease who is pregnate for the first time. a week ago she started to leak a bit of fluid and her milk came in. here it is a week and no kittens. they are still active inside her. she purs and is very loving still eating and drinking. how long should this last before babies come? should I worry about a dry birth? the fluid is a bit bloody but no infection. I real could use some advice.
Thanks

Do you know when she got pregnant? It'll be easier to determine the birth date at that point. Also, you need to be taking her in to get a checkup with your vet, if there are problems, she may have to go in for emergency treatment if something is wrong.

If possible, I would also set up an appointment to have her spayed to avoid this from happening again.
