Hi Jellybean
First, let me say, good on you for taking such good care of these two queens and like you, I think its not quite right (putting it mildly) that they should be allowed to be pregnant again so soon after having a litter. However, I believe you have got good advice from Kelly, Chris and Liz. Like Liz, I would say that the girl you showed us the picture of is around 5-6 weeks pregnant. Normally, gestation is between 63-70 days so quite a range (depending on the breed - siamese/orientals can keep one waiting for up to 70 days but my own queens tend to deliver the goods by day 68 or 69).
Please feel free to pm or email me. Hope it all goes well.
Best wishes and kind regards
