I need your opinion on pregnancy

Nov. 24 I had a period well Dec came around and me and my partner had sex Dec. 1 I was ovulating than. Well Dec. 17 my cycle came on two days earlier and I bled no spotting . Around January I started having cramps that are like mild and moderate I’m still having them. Than I woke up in the middle of the night one night having bad cramps that felt like I had gas. But I haven’t took a pregnancy test yet because I want to wait til my period come on I have 2 more days but I’m pretty positive I’m pregnant besides I’ve been craving sweets.
