Long story but please help!! I’m freaking out!

Here’s my story:

I had what I think is implantation bleeding over Labor Day weekend, Sept. 1st and 2nd. When I got home on the 3rd I took a test and there was a faint line. I tested every day last week and I got faint lines and positive digital tests, however my lines never got darker.

On Friday I went to the doctor and had a urine and blood test done. They said the urine test come back negative because a line did not show up in 5 minutes but a faint line did appear after 5 minutes. I got the results of my blood test today and my hcg level was 25. I am supposed to go back tomorrow or Wednesday and get my blood drawn again.

I took another test today and my line is very faint but you can still barely see it. I haven’t had any cramping or bleeding.

Can you have a chemical pregnancy with no cramping or bleeding, just faint lines until they disappear? Has anyone gone through this before? Do you think this is normal for an early pregnancy?

I have so many questions so please offer any advice you can! I am so nervous and scared.
