light orange dishcharge?!?

I am 15 weeks pregnant. I'm very stressed and have had a little cramping. nothing more than usual. this is not my first baby and this never has happened with any other pregnancy. I have a slightly orange discharge?? I am waiting for a call back from the on call doctor. i am freaking out. while I wait I was hoping someone could give me some insight. this baby is a rainbow baby. ive had 2 losses before this but they were earlier in pregnancy. there is no smell and its not a lot of discharge. im probably over worring loke i always do but i am nervous as hell. any other mamas have this?
