Help! Spotting....

I just noticed what I think to be some spotting when I just wiped, it was not directly blood- just orange/pink tint to my CM. Lately CM has been only white/watery. I'm freaking out because I've had a previous MC in April 2014. I have light cramps, not nearly as bad when I MC, and even less than normal AF cramps. Hubby and I had sex two nights ago, but there was never any spotting til this morning. Can't help but freak out! Any advice??? Thanks!
