I don't usually get tested till around 36 wks. They say it can change so the earlier you get tested the less acurate it is. I was + withall three and expect the same with this one. I get thrush real easy so I figure if I was pos with three why not four.

1st one bubs got the shot and had to be monitored for 24hrs before feeds.
2nd I got one dose iv (protocol had changed by then and mum got it not bubs) before bubs was born. She had to be monitored due to me not getting second dose of iv
3rd I got both doses in before bubs arrived and bubs didn't not need monitoring. Yay, I could feed and do my own thing.

As for the labor, I think I was only in bed, or not moving around much for the 2x5min of the drip. Otherwise I was as mobile as anyone else.

You might want to check about the earlyness of your test.
best of wishes
