Can I be Ovulating and Pregnant at the same time?

i just took a ovulation test which said i was ovulating, then i took a pregnancy test which shows a light line which means i am in early pregnancy. now i am confused, am i ovulating or pregnant. or can you be ovulating still if you just became pregnant. i am just confused, not sure what test to believe! :( anyone know if its possible to be both, and no i do not have 2 uteruses like rare cases. i am trying for child #4 and every pregnancy was normal with my other 3. what is anyones thoughts on this, just need some input what i should think!!! not sure what test to believe, i took 2 ovulation tests which both said i was ovulating, and 2 prego tests that both had light line to indicate early pregnancy! hmmmm! please help!
