Good on you for being able to enjoy the last few weeks, wish i could say the same! i am a few weeks behind you and i am not enjoying it much at all!
i guess it depends on your cicumstances and how comfortable you are.
I am drinking RLT, as it 'tones the uterus' i don't think it brings on labour, just getting the uterine muscles ready for a big workout!
Other than that not doing much, but i am looking forward to not being pregnant!
Enjoy your last 4 weeks.
