Less likely to be pregnant
Detailed Answer:
Hi
Welcome to HCM.
Irregularities in menses are common, based on the information provided, she is less likely to be pregnant.
But, It is difficult to diagnose pregnancy with only symptoms. Symptoms do occur. But it is difficult that you will get them very soon.
One of the earliest and simplest way to know that you are pregnant or not, is by using, urine pregnancy test.
Most experts advise that you should wait at least one day after your missed period before taking a home pregnancy test, though waiting a week is considered best. This can be tough when you are anxious to find out if you're pregnant, but waiting allows for a higher degree of accuracy when taking the test, as hCG levels rise rapidly in pregnant women.
It's best to do the home pregnancy test first thing in the morning, when your urine is most concentrated and hCG levels are highest. This test kits are nearly 98% accurate, so reliable.
With transvaginal ultrasonography, the diagnosis of pregnancy can be made earlier by 4-5 weeks gestation.
Hope this helps
Take care
