Hi StellasMum...
It does sound a bit concerning that your BP is up and protein in the urine together. But I would think your OB would have mentioned it if he / she was concerned?...

I definitely think that it is worth mentioning to your OB earlier than Monday, if only to set your mind at ease, kwim? He / she should be able to explain to you what the reasoning is & when to be concerned or not. If it were me I would want to know.
It may be that the absence of any swelling means there is nothing to worry about
Good luck hun hope things are all well for you
