I have a mare that was scanned in foal at 14 days then due to things out of my control was not scanned again until 35 days. This showed she was carrying twins so vet pinched one. A few days later scanned again and no embryo's present so look like both were lost. She was given a prostaglandin injection to clear everything out, as the vet said, but now 2 weeks later her udders have swelled and she is producing milk. We were hoping to try again on her next season but just wondered if this is normal or what has happened to her. Any advice greatly appreciated.

Hi Tracey, sorry to hear your mare lost her pregnancy. Is your mare coming into season? Her body still believes she is in foal, even though she has lost the pregnancy, the hormones take a while to settle down again. I would give her some time and if things do not settle down get a vet to ultrasound her again. It is not common (in my experience) for mares to produce milk so early, but hormones are funny things and can affect mares differently,

Once 35 days of pregnancy are passed, it is unlikely that the mare will come back into estrus - even after receiving PGF2a - until 120+ days after she was originally bred. This is as a result of the secretion of a hormone of pregnancy called equine chorionic gonadotropin (eCG) that causes the production of secondary follicles and CL's.

You may get lucky and have her come back into estrus, but don't count on it...

There are several possibilities related to the mammary development which are hormonally linked. If you have concerns, have your vet check the mare again.
