Late period

Dashia

Hello ladies so, I was suppose to have my period Friday but Mother Nature decided not to show up it’s now Sunday and still NOTHING I’m not having any cramps Friday it looked like I was spotting it was really really light I thought that was it but nope I have been feeling nauseous I’ve had severe back pains and my boobs is tender when I touch them ☹️ and yes me and my husband has been having unprotected sex a lot lately .... could I be pregnant? How long should I wait to test???

Kinda nervous here 😭😭😭😭
