Have you been counting days since she went in?
Also, Walmart has $4 fleece throw blankets that you can use on your furniture for her to lay on as a compromise to britches. If you are really lucky you may be able to find them at Big Lots for as low as $2.50
I'd second what lvoss says about fleece - my pup is in heat as well although we're 10 days further in (Liyah started on the 8th) than you are :D. I found a bolt of fleece in Walmart's remnants section this week - cut 3 throws from it - actually thicker than the pre-made throws. The bolt cost 2.84 - quite a deal!
