Slightly freaking out.

I've been having a wet ness in my underwear for the past two days that is clear and very liquidy. And today it has almost a bleach like smell. So I called the doctor to see if I should go in and they told me they'll call me back within 30 minutes. Then after 30 minutes I called again and now they've said wait another 15 minutes and if I don't get a call back to call them yet again. I'm a ftm at 31+3 and only getting more worried as the time passes...

Any mamas who's been through this have any advice?
