Question for cow breeders (non zoo breeding)

[Gunslinger1X]

Recently got a rescued cow, rescuer said she wasn't with a bull that she's aware of, however yesterday while cleaning mud off her udders I got a face full of milk.
From what I've read online that means she is due to have a calf within 45 days, can anybody confirm this?

Never was with a bull, hmm what have you been doing with the cow 45 days earlier?
By the way a vet should be able to answer this question much more precisely.

It turns out there is a possibility that she was with a mini highland bowl around February which would be the right time frame

As far as I know, then women and cows have identical pregnancy hormone, so a standard ‘human’ pregnancy-test (HCG) will probably work here too.
EDIT : The urin-tests made for cattle, cows, goats measure estron-sulphate,

• Abdominal ballottement (bumping).This can only be used in females that are five to seven months into their pregnancy. To feel for the fetus, use the following technique:
  • 1. Place your hand or fist against the lower right flank region of the abdomen, then
  • 2. Make a short, vigorous inward-upward thrust and keep your hand in place. You will feel the hard fetus come back against your hand. The amniotic fluid will allow the fetus to recede against your bump but fall back in place almost immediately.
  • The size of the fetus determines the effectiveness of this technique, which means that it can only be done when the cow is over halfway through her gestation period and not one and a half to three months (45 to 90 days) post-breeding. Because of that it's not an effective technique for early-detection pregnancy nor for large herds that need to be "preg-checked" in a short matter of time. It's best for small herds and for producers that would want to feel for a fetal calf that is only a few months away from birthing for curiosity's sake.
• Fetal heart beat. This is best performed after the sixth month of gestation, though detection can be unreliable as it is not as certain as with other classes or species of farm animals as in cows. Use of a stethoscope is recommended even though pressing an ear against the right lower abdominal region and listening will also yield good results. The fetal heart beat can be distinguished from the dam with its greater frequency and higher and lighter pitch. This method is not recommended if the cow is not cooperative nor accustomed to human touch. Do this only on cows or heifers that are accustomed to your touch and you trust each other enough to be able to do this without a stethoscope and without getting kicked. Like with bumping cows, this can only be done on those cows in the last two-thirds of their pregnancy, and is not ideal if early detection of pregnancy takes higher precedence than mere curiosity and a willingness to wait for a long period of time before being able to determine pregnancy of a cow or heifer.
• Fetal movement. Patience is much needed to observe voluntary fetal movements on the right side of the cow through the abdominal wall because you just need to wait see such movements. This can only be done when the cow or heifer is in the latter half of pregnancy, and is certainly not ideal for either early detection or if you wish to have results without waiting for either the right time to detect nor to see any results.

How to Tell if a Cow or Heifer Is Pregnant: 9 Steps

Determining pregnancy in cattle has many benefits. You can get twice the meat then when the cow wasn't pregnant and a producer is able to know which cattle will be the keepers and which will need to be culled as soon as possible. All this...
