Did your pregnancy symptoms come & go?

Carola
Hi. Pregnant in week 6+ (first pregnancy and I am 39 years old) and I had very sore boobs until about 5
 days ago then they stopped being tender and swollen. During this period I had very poor sleep as well (stress at work). Now the boobs are back being tender and lumpy. Is this something any of you have experienced? Should I be concerned?
