The SAME thing happened to me. I got a fill to 3.0, from 2.8 and came home, a long 5 hour drive and could munch down a huge rice cake with cheese, I almost swallowed it whole to test it. There is a post here somewhere of me freaking out.

BUT THANKFULLY, I tightened up after a few days or a week and could then I could really tell that I was given a fill.

Don't dispare yet, it might tighten up and you will be losing again.

If you don't tighten up after a week or two, then there may be some explanation as to what happened. I don't know, either the needle didn't get back into the port membrane when the saline was put back in or ??? any number of things.

I hope things tighten up for both of you the way it did for me.
But I know from direct experience that this was a very strange occurance.
