Feeling pregnant... I don't know

D
So I had a chemical with bleeding on 3/3-3/4 I have all the same symptoms as when I was pregnant... My pregnancy symptoms faded that week that I had a chemical my levels went down quickly I'm also wondering do your levels have to go back down so you can conceive again? Or does it matter? Anyways I'm having all the symptoms as before but still getting negatives I had a ton of cm a few days after the bleeding it was EWCM And now again 2 weeks later same thing as far as the CM. I don't know what to think am I testing too early?
