So two week wait

I had un protected sex two weeks ago and I've been expirencing cramping, clear urine (I rarely drink water) , different bodily smells, and my stomach has been twitching for some reason. Does anyone know what this could be? pregnancy maybe? So far I've missed 3 days of my period which I usually end my period in 3 days and I don't think I'mma get it soon. Everybodys body is different when it comes to pregnancy some get symptoms earlier and some later? Any advice? I'm really nervous so no hate.
