Are thier any ways to tell if a heifer is pregnant when it has only been 24 days since she was AI? My heifer came into estrus 2 days early and was bred by AI she has acted differently since about 5 days after that; she came back into heat today (I think), 3 days late, she was swollen and stood still to be mounted by a steer. The strange thing is he didn't constantly mount her like he would before she was AI. For the most part he acted like she was not in heat at all. She would also mount him about as much as he would mount her but, today I didn't see her mount him at all. She did rest her chin on him like she was going to mount him but did not. The weather here is changing it's very rainy and getting cold I don't know if this affect anything or not. I don't know what to think. I did not have her rebred today because I'm not sure if she is pregnant. Has anybody experianced anything like this? What should I do?
