Hallow Dear,
I can feel your frustration from your query.
There are various ways to detect
pregnancy. The cardinal symptoms of early pregnancy are:
1. Missing period
2. Frequency of urination
3.
Nausea &
vomiting with aversion to the food.
4. Breast changes which include engorgement with tenderness, dark discolouration of nipples &
areola with increase in areolar size, small tubercles under the areola (Montgomery's tubercles) and secretions from the nipples.
It takes about 10-15 days after missed period for the last 3 symptoms to appear. By that time even clinical examination by a Gynaecologist is also quite diagnostic.
So just see whether you fit into this picture. However, early pregnancy is never diagnosed only on symptoms and need some confirmatory evidence.
After 8-10 days, urine pregnancy test done on the overnight first morning urine sample is quite a reliable test. Earlier, these tests may be false negative. By this time, even
ultrasonography also can give you direct visual evidence of the pregnancy.
Beta hCG test is very specific and highly sensitive test and can give you the results about pregnancy even few days before missing a period.
I feel instead of being stressed in just guess works, it is better you choose one of the above mentioned options to confirm the diagnosis of pregnancy.
