Don't know how to feel!

So I had a miscarriage on Sept. 10th. I was almost 2 Months preg. But the baby stopped developing at 5wks 4d. Here I am again 6wks pregnant not wanting to get too excited because of what happened to me before. My boobs aren't as sore as last time. I do get way more nauseous than last time. I've just been having some mild cramping that has me a little concerned. My first doctors appt is the 30th and i just want to hear a heartbeat. I didn't get too with the other pregnancy.
