7 weeks pregnant but breast soreness reduced.

7 weeks pregnant now but breast soreness has reduced to 10-20% pain compared to initial of 85-90%. I had mini cramps here and there during the 1st few weeks of pregnancy but now is almost gone too. However there is no blood spotting or brownish discharge. My first scan is on 22nd Feb. Should i be worried? #advicepls #pleasehelp
