Hi, I've been researching this lately too. Are you drinking RL tea or taking the tabs? If you google it tells you what the recommended dose is so you'll have to work out what mg you are taking in (depends on the brand) and then see if you can up it. I've just started taking 2 tablets/day which is what the bottle says (Herbs of Gold) but from memory from last time the total allowable/recommended was more than this so I upped my dosage towards the end.

Also - hope you don't mind me asking, what do you mean that your window for VBAC is running out. Do you mean you are worried you are running out of time? I'm hoping for a VBAC this time and that's my fear too AND my baby is breech still.
