Bloody show! Need advice 😩

So just about an hour ago I went to the bathroom to pee and when I wiped there was a bit of blood and a little bit of discharge. I quickly called my OB to make sure everything was ok and she said at 35 weeks it’s really not a concern but that I could be having contractions without even knowing yet. I’m just curious how quick after a bloody show did you go into labor? I’m so nervous because just earlier I was saying that I had a feeling he was gonna make an early appearance bc I just felt off all day. And I just had an appointment today and found out he was head down. They haven’t done any cervical checks yet we were waiting until week 36. I also haven’t lost my mucus plug and my water hasn’t broken yet. the blood has stopped so far.
