Hi there
I wouldn't take your lack of BH as a sign it would be safe to take the EPO so early. I didn't have any that i noticed when i was pregnant with DS and then wham i went into labour after DTD at 37 weeks, this time occaisionally i will get them and then i won't notice anything for weeks on end. Maybe the best ppl to ask when it is safe to start is a Naturopath or someone similar, i just always remember reading that natural supplement can be as dangerous as normal medications without the right information....just to be on the safe side.
Hope you get the VBAC you want!
