stressed to the max. needing some advice!

Wedding is in 13 days and me and fiancé are redoing are INTIRE house! New floors, paint, counters, furniture, ext... And now I just stepped on the scale and I saw I gained a good 10 pounds. I haven't tried my wedding dress on in a month and it's tight fitting and now I'm scared I won't fit in it... How do I loose a couple of pounds fast? Should I be worried? Needing advice bad. Thank you in advance lady's!
