Brown spotting and cramps for a week

I've talked to my dr and she did a blood test and told me my levels were fine (7,000ish) but we are going to another one today. Anyone else have this? It's like I can't get excited about being pregnant because I'm waiting for it to get worse. I am 5w4days today. My first appointment isn't until July 7th. I'm just ready for this to stop and start enjoying this. What do you guys think?
