You can relax a little. We were implanting last wk & imagine how floored we were when the embryologist said 'this cow is 8 1/2 months pregnant'! She'd had the CIDR, lut & whole set up to be a recipient. Our neighbor had set her up. Thought she'd had a calf because she had sprung, bagged up etc. They hunted the field, watched her closely for a month. Figured she had had the calf & they couldn't find it. We could've done the same thing. They know what they're doing. So, it isn't certain that you'll lose your pregnancy.
Depends on how far along the pregnancy is.
Another story of interest. We had a cow we had seen in standing heat more than once. So come breeding season we gave her some lut to breed her. Were pretty upset when we found we aborted her. So now, the rule at this place is no lut unless we test for pregnancy first.
