I'm not a medical professional, but I think the odds are that you'll be okay. From what I've read, it seems that the major risk with Tramadol in pregnancy is with long-term use at high dosages, which doesn't sound like it applies to you. Women do all kinds of things before they know they're pregnant and 95% of the time, everything turns out okay. I would, however, not take any more, and I would tell your doctor.
