1 negative and many faint positives

I'm 16 dpo, I started testing 11 dpo and started getting faint positives. The day I would have started my period. I got up at 6 am peed in a cup and took 3 test. A clearblue digital, first response, and a cheapie. I stood there waiting, feeling like I was finally and really going to know if I was pregnant! The first response and the cheapie had faint lines, like they had in the days before, but I wanted to see that word on clearblue - PREGNANT!!! then it happen it said pregnant!! I was so happy I grabbed that test up and ran to my husband, waking him up. I got the cutest smile from him. I'm happy everything is good. I even notice some symptoms. Then today came. And all my Hopes came to a stop with just one little test. I got up this morning peed in a cup. Got my cheapie test out and dipped it. I'm obsessed. But it was faint but seemed fainter then the others. So I got my extra clearblue digital out and dipped it. And then I seen it. Not pregnant. Everything just stopped around me. Now I dont know what to do. Do I just except all the faint positive and say I'm pregnant and just take that one only one digital that was a negative and say it must have been flawed. I am a very impatient person. So my sweet husband took money that we could have used on other things and bought me 3 more first responses for me to test in the morning. So I am just hoping for a darker positive.

Has anyone ever had this happen?

How can I let just one little test ruin all my happy feeling.

I have miscarried before but my body wouldn't let the pregnancy go. My hcg levels were very high but the baby didnt match the levels and there was no heartbeat.

I dont feel like it's going to happen that way this time. But a different fear has come over me.
