Pregnant Bengal

Hello, i'm new to the site, and i'm hoping you can give me some advise. I have a pure bred bengal cat who we believe to be about 4 weeks pregnant. she was at the stud's house for about 3 weeks and we know she was breed.  She already has a big pregnant belly, she is very loving, eats like everything she can get ahold of. her nipples have become big and pink.So i guess my question is, " what should i expect to see in the coing weeks?"

Hasn't your mentor gone over that with you? Or the studying done before breeding cats & fellow breeders you've befriended?
I suggest you pick up several breeding books asap. There's one by Dan Rice that's good- the complete book of cat breeding, also Robinsons book on genetics is a must have
There's also the cat breeders handbook, breeding pedigree cats...to name a few

I'll diff. Look into getting though books right away. But does anyone have in personal advise?

Your mentor is the best person to ask, she knows her lines and how the cats behave (some lines still call while pregnant for example)

She'll keep getting rounder, eat more. Possibly some morning sickness, other than that behaviour is pretty much the same. My girls are just as crazy and active, poor babies grow up in a tumble dryer as the girls race around 

There's also a sticky at the top of the forum with links on pregnancy

I notice you said you 'believe her to be about 4 weeks pregnant' I hope the dates were properly recorded? They are needed for the stud form, and of course for your due date. 

I enter mine into the pedigree software soon as we know matings have taken place, and when studded out the breeder emails the dates along with the official stud forms.
