So the vet came out four months ago to check my rescue to see if she was pregnant. At the time her cervix was tight but no foal could be seen or felt. She was with the stallion up until the day we bought her so she could have been less then 16 days pregnant. Vet also said that with a malnurished horse you can't see a foal as much as 30 days after conception.
The vet came out today, for a re-exam of her stools and possibility of mastis(sp?). She looked at her udders and felt them, saying "No, what you have is either she was pregnant and we couldn't see it, or false pregnancy." She went to her car and got a sleeve since she did not have her ultrasound.
Lena's cervix is still tight, her uterus falls off the pelvic rim. Vet said she is more then likely pregnant, and an ultrasound also wouldn't see much during the 4-8 month period. She said to go ahead and do vaccines as if she is pregnant. So, now we all know, around February next year I'll probably be starting a foaling thread. *Sigh* Glad that debate is over.
