I bought a mare in November people on the yard told me she was pregnant so I called the vet out he did blood tests and they came back negative so I carried on with her as normal months went by and her weight gain was unreal and she's not a greedy horse at all.so I called the vet back for some advice he said if she was over 100days pregnant at the time he did the bloods then there's a chance that they where incorrect and she possibly is in fact pregnant and to just wait and see she should only have 4wks left. Any way we needed a black smith 2wks ago and we asked his advice and he said yes she is defo in foal I give her 3wks max. So now she is enormousness and eating everything in site her belly looks like its dropped and her vulva looks larger than it did a few wks ago last wk there was a mustard y colour blob of paste type substance in her straw and to day in the 3rd wk of the black smith tellin me she had 3wks left she had a white/cream sticky looking discharge coming from her vulva how long would you say she had left her appetite is still huge she hasn't bagged up yet but that can be normal so I've been told ??????
