Just Riding Along...

K
I will know via ultrasound on Wednesday whether I am 7, 8 or beginning of my 9th week. I think my  July 15 due date will stand (meaning I'm in week 7). I'm scared because I'm cramping (and constipated) and sometimes my breasts are sensitive but other than that.... Nothing. 
Has anyone else had to invest in new bras? I went from a 36B to a 36C! (Yes it really fits and I think it'll help with soreness).
