I don't like your chances of pushing bub out like that. But it does feel like that when you are in labour. You are right though, straining too much can and will give you hemorrhoids (sp) this can also happen with the pushing in labour though too.

Try and up your fibre intake, and make sure you are drinking plenty of water. Trust me, there is nothing like going into labour constipated. My labour with Tehya was held up because I was so badly blocked up (sorry tmi)

And hey, your 36 weeks preg, full term is anytime from 37 weeks. Getting out of those last few weeks is great
