The best way to find out about pregnancy
is by doing a urine pregnancy test. The symptoms of pregnancy cannot be relied on at such a early stage of pregnancy. Alsowhen one is apprehensive about pregnancy then they tend to feel them even if pregnancy is not there.
The spotting can be implantation
bleeding and that means that you are pregnant. But nothing can be said for sure at this stage.
My advice is to wait for your mensus, if it does not come on the expected date then do a pregnancy test.
Its best to confide in your mother.
Hope for the best.
