Miscarriage?

DanielleRM
So after having some spotting on Friday I decided to test Saturday morning, to my surprise it showed up positive. I took two clearblue digitals with the weeks estimator which both said 1-2 weeks. 
I continued to have spotting through Sunday. Sunday night I woke up to some decently bad cramps. I also wasn't feeling any symptoms anymore so I decided to test again this morning. I took the same kind of test and now it says not pregnant. Is it safe to say I miscarried or should I test again tomorrow? 
My husband and I are new to this and very upset and I'm just needing some advice on where to go from here. Thanks.
