I have a 13 yr old TB mare - has only had two foals and it has been two years since last foal.
We bred mare after she had ovulated - vet could not make it day before.
She was still standing for my 13 yr old gelding -which was just gelded last year- right before vet showed up. So I was hoping we were still in the window.
A few days before 21 day check- vet is just out of school, not comfortable checking any earlier-
I noticed her following my gelding around and holding tail up. Not peeing or squatting -just acting weird.
Vet comes out on Thursday - ultrasounds her- she has two follicles on the left, nothing on the right. The follicles are both about 27mm.But she says there is a cyst in there! It was not there when we bred her 18 days prior - has anyone seen one just appear?
We check her Monday- one follicle about 25mm.
Check Wednesday follicle is a 23mm.
Check Friday follicle is a 21mm. Cyst still there.
We decide to leave her alone and check her again in about 14 to 16 days.
My mare never got to where she would pee or stand for my gelding during this time like she did on the heat we bred her.
My question is do you think the cyst is the baby and she had a weird cycle- or is it a cyst that just appeared?
Thanks In advance!

I've never had a cyst appear right after a breeding. However, are you absolutly positive the cyst wasn't there when she was bred? You should check at around 26 days for a heartbeat.
We made the mistake of thinking a mare was pregnant, when really, it was a cyst, because we failed to map it before breeding. So now we know to check for both the cyst AND another stucture

The vet should ideally map her cysts so it's not getting confused with a pregnancy. Why are follicles shrinking? 27mm to 21mm. If she was covered after ovulation and did not take and was following your gelding around 21 days later then it's most probable that she was in season and since it's 21 days since she last ovulated she should be close to ovulating again or have ovulated already. I've never heard of cysts just appearing and but a vet could mistake a cyst for a pregnancy. The plus side though is that a cyst does not develop a heart beat

I am not absolutety positive it was not there. It seems too big that even going from left to right horns checking ovaries and follicles we would have seen it. We will start checking her again on Friday to see what is going on.
I got another Vet's opinion about the shrinking follicle and he said most likely she ovulated the other one instead of absorbing- so the other one shrunk. I don't quite buy that though, because she gets 48mm to 50mm before she ovulates, and both follicles were only 25 to 27mm. Also, only three days from two follicles on one side to just one and then shrinking.
I will let everyone know after Fridays check.

Well vet could not come till yesterday- Tuesday.
It was a cyst that we somehow missed - but it seems to have shrunk some and it is in the right horn I think she said.
Anyway she is just starting her cycle maybe a 10 mm follicle. So we shall try again!
Thanks for everyone's input.
