my british had a litter 3 weeks ago, she had mucous coming away on the sunday and didnt give birth untill the following friday, she likes to keep me waiting.

For now i would keep a close eye on her as birth could be very close, if the mucous turns very bloody or brown ring the vet asap.

Iam no expert but if you need any help/advice or your just worried i can pm you my number, i know how nerve wracking it can be however many litters youve had.

I hope everything goes well for you
