Maiden mare due to foal
I have a 5 yo AQHA maiden mare who is 333 days today. She has been bagging up for 3 weeks, has been dripping white thin liquid for 2 weeks, tail is loose, has been rubbing her butt against anything sturdy for 2 weeks and is all around miserable. For the past week I have been keeping watch on her throughout the night, she lays down and pants heavily for anywhere between 20 min - 1 hour, rolling from "sitting like a cow" to full on her side, she will kick at her belly and moan. Around 6:30am every morning she will stop, eat, and act like nothing ever happened. She is still voiding and having stools, drinks and eats well. I have been testing her milk yesterday her calcium was still 200 but her pH dropped to 6.8, I check again in the night and she was Ca 200 pH 6.4 and yellow on the edges, I was up every 30-40 min checking on her. No baby! I tested again this morning and pH was back up to 7.4. She is driving me crazy! Any suggestions on what she's up to?
