Pregnant but no symptoms?

I got my BFP on Friday evening and last month had a chemical pregnancy and with that I had bloating, sore boobs, horrible allergies, ect but I also cramped real bad which led to me bleeding which made me realize it was a CP. with this one, I'm farther along this time than when I tested last months. I'm 5 weeks 5 days and the only thing I'm experiencing is a missed period, sore boobs every now and then and some very, very mild cramping every once in awhile and fatigue. I haven't called the dr yet since it's the weekend, but I would know if I miscarried wouldn't i? I would be cramping and bleeding. I'm so afraid of something happening or not really being pregnant since my symptoms are so minimal. Anyone else had this and had healthy pregnancies?
