blood thinner & epidural ?!?

Jaime
I have been on lovenox this entire pregnancy and am making the switch over to heparin soon, at 36 weeks. I am concerned (after trolling the internet and reading horror stories), I will not be able to get an epidural. My dr has never mentioned anything about it, and I'm definitely going to mention at next appointment, just curious if anyone has had experience with this??
