Hi!
Don't be terribly worried. MOST things do not pass through the skin in any amount large enough even to enter the blood stream, so it is very likely that your worrying about the chemicals is more harmful than the chemicals themselves!
It is of course adviseable to avoid contact with skin, and eyes, and not to breathe the fumes, but your body is well designed to protect your little baby girl!
Good luck!

If you are very worried about it, don't hesitate to call the doctor. I think the baby will be okay, though, as it wasn't constant or repeated contact/breathing of the cleaner. It's amazing how resilient unborn babies are. Best thing to do is call the doctor, though.
I hope all is well!
