Thank you onetwothreefour
I wasn't doing it 4x a day but I was doing it daily abd it was dropping every day, the thermometer I use is a digital one brought from Lloyds pharmacy, it is a good one
I had made an appointment with the vets for this morning to get her checked over to be on the safe side, but I have good news, 15 minutes after checking her temp last night at 8.30pm she started whelping

and at 11.35pm puppy number 1 was born followed by puppy number 2 at 12.14am and puppy number 3 at 2.04am, so we have 3 beautiful strong healthy pup's, everything went plain sailing and mom and puppies are doing fantastic
