I just don't know

So I'm due for af tomorrow, and this morning I started spotting, so I assumed I started af. While I was leaving work I went to check and no more spotting. My tampon was completely dry. My boobs are hurting so bad, I am waiting till my actual start day to take a test. I'm trying so hard not to over think it. My husband and I have been trying for a few months, and everytime I turn around another one of my friends are pregnant. So I'm starting to get upset lol and frustrated. any thoughts?
