should i be worried ???

I am 5 weeks pregnant and the last few weeks I've had cramping and sore and enlarged breasts. The last few days I've had no cramping and no soreness. I dont think I'm tired (more than usual!!) and dont have sickness although I dont really have an appetite for anything. Anyone else had sore breasts that have then dissapeared this early? I'm worried that its a bit early for the soreness to stop. I know people are saying that its lucky not to have symptoms but its worrying too. Does anyone know when/how long breast soreness is a symptom for? many thanks and love to you all expecting & ttc❤️
