Hi there!

First of all, I'm not an expert.
But I found some info somewhere where it actually suggested drinking RLT not just in the weeks leading up to birth but more importantly to make a strong brew for when you're in labour. I can't find my source, but here is what was recommended (fortunately I wrote it down): take 1 ounce (28g) of Raspberry Leaf Tea (loose leaf from the Health food store) and cover with 1 pint (570ml) of hot water, let steep for 30 minutes and drink as hot as possible either on the way to hospital or when you get there. It came with the warning not to drink it too early as it might get things moving pretty quickly. Apparently it came from a Scottish herbal remedy book.
I have no idea how credible this info is, but I think I might give it a go.
So if you don't want to buy another bottle of tablets, you might want to give this brew a try instead. But again, no responsibility taken here, I have only read it and not tried it myself.

Good luck with everything, though!
