How far dilated is it okay to be at 33 weeks+3days?

So I promise I'm trying not to freak myself out, but I've been having some strong BH lately and just felt like complete achey/crampy shit today. I won't see my doctor until next week, so I decided to feel for my cervix to see if I'm dilating(it's so low right now that it's easier to reach than putting my socks on), and to my surprise I can easily place two fingers at the opening of my cervix... Should I worry? I know that my check might not be as accurate as my doctor's, but is there anyone else out there who has started dilating this early and their doctors tell them it's okay? I know everyone is different, and I don't want to google it and have WebMD have me feeling like I'm gonna die lol
