Help ease my mind here

Okay so we aren't exactly trying per say, we were told to go see a fertility doctor before trying to get pregnant again. Well according to glow I won't ovulated until next week, yesterday was a 7.3% chance from what the say. We had unprotected sex not thinking at all, and my cm is clear. I would love to be pregnant more than anything but worried about what might happen(past pregnancies have been a problem). I know it sounds stupid to ask but are our chances still pretty slim of getting pregnant this go around?
