Cramping at 6 weeks?

hey Guys! I just found out I was pregnant again this morning after my early miscarriage (7 wks) back in December. I got so tired of testing and getting bfns that I waited until I was a full week late for my period to test. I'm 6 weeks now but I am noticing light cramping on my sides, hips, my lower back. I'm also feeling kind of cramping near my rib cage like on my breast plate? I set up a midwife appt for Wednesday just in case anything is wrong (I'm not bleeding). I'm just freakin out because I had cramping in my other pregnancy too and we can see how that turned out...anyone else have a similar experience and can put my mind at ease??? it would be much appreciated. *this post is cross posted, in desperate need of replies.
