Am I Pregnant?

Hi loves! A couple weeks ago, more specifically 10 days after my cycle I started spotting with brown blood. That went on for about 2 days then stopped and started back up last week with light red and brown. I’m supposed to get my period tomorrow but I don’t feel anything. I have cramps but they feel a bit differnt than the regular ones. I’ve taken a test and it was negative. Does this sound like a pregnancy? What are you experience’s. Also my husband and I only use the pull-out method. 🤷🏼‍♀️
