Help not sure if my mare is in foal

Hi can any one help me in finding out if my mare is in foal had the vet do a rectum internal and she said she could feel nothing my mare was used as a foaling machine and has had 5 foals to what I know off
I got her 10 years ago and never wanted a foal but I was told 3 weeks ago a colt got into the mare's field.

I think her shape is wrong to how she normaly is has with been a full welsh when she is over wieght she is round allover not just in the belly part

I have photo's showing her size

Thank you

If you want to know for sure you need to consult a vet or you can wait a few months and see what happens.

Hi had the vet out and she did a rectom internal and said there was nothing there, if she is this would be her 6 foal has she used to be breed machine I know a colt got into the field last march april time last year

Umm....... if the vet said no then there isnt a baby...... and she does not look pregnant at all.How old was the colt? Was she in heat? Why didnt you get her checked earlier?

Only found out last week thank's to this person that let his colts run about and then left the yard and left the colts unatended they were about 18 month's old, so got the vet in stright away I have read that a old mare that's had foal's are hard to detect if in foal by rectol internal I just hope she is not as can't aford to keep another mouth to feed

Why didnt you have a vet do somthing else then? And if she is that far along then you can feel the baby when you stick your hand.....in there.......

Ok thank you

Some more photo's thank you

Here our vets do an ultra sound around 3 months of pregnancy tomake sure theres no twins and to confirm pregnancy. You could try this?

There would be not the slightest external sign in a mare only three weeks into a pregnancy. Her belly would not look any different, her udders would not look any different. Most mares don't show any changes in body shape until nearly seven months along or later. Your best way to tell if a mare is bred is at or after day 21 (three weeks) a vet can do a rectal palpitation - which you have had done, and the vet TOLD you there is no baby. If you are still concerned, like someone mentioned, shell out the bucks and have an ultrasound done.
