Try not to panic too much and well done for managing to put money away for a 'rainy day'.
TBH I hope you will be 100% ok, thats the real issue here. I had this ( a while ago, about 9 years ago) its a bit uncomfortable but the relief of an all-clear is what you are really striving for!!
By the way, I had sex after a week, Dr was a bit cross when I ended up getting an infection (not an STI, I wasn't escorting then, and with OH, but we hadn't been together long and still at that stage of wanting 'it' all the time) oooops
I think the 6 week thing is just to be safe but it may not be as long as that.
Anyway, rambling here, good luck and enjoy your holiday. Hope you are going somewhere nice and hot! xxx
