How long did it take you?

How long did it take yall to get a positive test? Like I know it takes some people longer for the hcg levels to get high enough. Im wondering because I took a test two days ago and it was negitive. I have been ttc... I know it took my friend two weeks after her expected period and im just not wanting to lose hope. I was supposed to get my period yesterday/today and havent gotten it.
