Reason for concern?

So I'm feeling like I want sex tonight but I've been really afraid of preterm labor. I'm 33 weeks and 3 days and I know that sex is safe in pregnancy but I've lost my mucus plug so to me it's a sign that I shouldn't have sex until it's a safe point in time where if it did cause anything to happen then she would be healthy. I've tried looking out for any other signs that labor is near but besides some nausea and back ache I haven't really noticed anything. And my back ache isn't even often, just after I over do it a little with packing and stuff and the fact that I'm 33 weeks pregnant. At least I hope that's why I have back pain. Is this even a rational concern or should I just go for it since they say your mucus plug can come out weeks before labor is near? I know you all aren't doctors but I just need others to weigh in on if I'm being ridiculous..
