Hi i am trying to get pregnant by the 2md baby .. after the 2day of trying i started feeling very dizzy and tired also yesterday morning and today morning i vomit in the morning .. my other son is 8year old.. does it means i'm pregnant?

Maybe. Maybe not.: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result if done correctly. One can test about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. An Ob-Gyn doctor can evaluate any persistent or worrisome symptoms.
