I wouldn't be too worried, fiberglass in general is a pain to get rid of as long as you don't inhale it, or let it get inside you body through cuts and such and don't let it linger in your skin for a long time, you should be fine.
I spent my apprenticeship crawling through roofs with fiberglass insulation. After being in contact with fiberglass the fibers get stuck into everything, tools, clothes, walls carpet everything!
(think of them as very small acupuncture needles) even if you scrub yourself there's most probably going to be fibers left over. Best result for cleaning after using fiberglass is to have a really, really freaking hot shower/bath/sauna, so the pores of your skin open up and release the fibers that are stuck in you.
As for fibers in clothes, that was always a little more difficult, i usually just used a household vacuum cleaner and tried to remove as much as possible that way, but this was on hard wearing cotton drill clothes, so that may not be a good idea for finer fabrics, but worth a try. Washing in hot water a few times would also work, or even hanging out your clothes and linen and giving it a good whack. Lint removers (the sticky roller thingys) or plain ol' masking tape is also good for removing the fiberglass fibers.
I cleaned my uniforms alot in my apprenticeship if u didn't already guess
Hope this helps.
[EDIT]
Almost forgot to mention. avoid washing clothes with fiberglass in them with anything else, more often than not fibers will spread and end up in places you really don't want them in
