This depends on how she was bred. If she was bred by a good fertile bull, then no. But, if she was bred artificially (through artificial insemination), there's a 30% to 40% chance that she won't catch and will go into heat around 21 days after being bred.
Other factors, on the bull side, include that the bull may NOT have been a good fertile bull, but one that is infertile or unable to copulate to successfully settle her. Bulls like this are those that a) have poor conformation, or b) have not been semen tested recently.
On the AI side, there's a chance of human error, that the semen was deposited in the cow's bladder and not her uterus, or the semen was deposited not deep enough in the uterus, or that the ovum in the cow's fallopian tube died too soon and the sperm got there too late, as a result of breeding her a little late on schedule.
On the cow's side of the problem, she could have cystic ovaries, or is too old to be bred, or has been bred too soon after she has given birth, and consequently couldn't settle right away.

How do you know when a cow is ready to be bred?
When she goes into heat or estrus. Check out the related question below.
What is oestrous in dairy cattle production?
Oestrous is when the cow shows "heat" meaning she is ready to be bred.
Can extreme heat cause a cow not to cycle?
Yes, in a way.
What is a pregnant cow called?
A bred cow or a pregnant cow, or, in the dairy industry, just a cow. In sale barns, if she has a calf at side, she is also referred to as a 3-in-1 or a three-fer or suckling bred cow. If she's lactating, like in a beef or dairy herd, then she's called a nursing bred cow, lactating bred cow or bred lactating/milking dairy cow. If she's not nursing or lactating, she's called a dry bred cow non-lactating pregnant cow if you really want to get technical. In the dairy industry, a lactating heifer that has already had her first calf is referred to as a first-calf heifer; once she has a second calf she is generally referred to as a cow. In the beef industry, a heifer that is pregnant with her first calf is called a bred heifer.
What is another word for a pregnant cow?
Bred cow.
When can a cow be artificially inseminated after she has had a calf?
It's just like knowing when to put the bull out with the cows: When they're not pregnant and are ready to be bred. Most often it will be the cow herself that will tell you when she is ready to be bred, but you have to judge when the right time would be to AI her. Ideally 45 to 60 days after calving is when you should consider getting her bred. AI needs to be performed 12 hours after her first signs of heat.
How do you know when a cow will be ready for conception?
A cow is typically ready for conception when she exhibits signs of heat, such as mounting other cows, increased vocalization, and a swollen vulva. This usually occurs every 21 days. Additionally, monitoring her reproductive cycle and using tools like heat detection patches or activity monitors can help determine the optimal time for breeding.
When do ponys go into heat?
Ponies will have a heat cycle every 2 to 3 weeks during the longer, warmer months of spring and summer. If they are not bred or do not conceive once they are bred they will go back into heat within a week or so.
How many times does the Bull mate with the same cow?
Only once is necessary to get her settled. However, during a heat period, one cow can be bred to multiple bulls (if there are that many) more than once during her heat period.
What is a cows mating cycle?
The act of conception for the purpose of producing offspring. A cow can only conceive if she's bred to a bull, not another cow. See the related question below to find out how it's done.
If a dog is not bred on a heat cycle how soon will she come in heat again?
Answerit depends on the size and breed of dog, but usually large breeds take about six months to come into another heat cycle.
What is cow called when it has not produced a calf?
A cow that has NEVER had a calf in her lifetime is called a Heifer. A cow that has not had a calf YET is a heavily pregnant or heavy-bred, or a short-bred or long-bred cow. A cow that has not had a calf during a calving season is called a barren cow, an open cow, a cystic cow, a cull cow, a meat/slaughter cow, a poor cow, a free-loader, etc.
