Looks like I won't need synto afterall. Turns out my waters aren't leaking - just a watery show over 12hrs or so. And contractions have started on their own. Being upright makes them stronger but seeing as it's night time I wanted to get as much rest as I could before actively trying to get labour going.
It's just before 4am now & I don't think I'm getting back to sleep. They're 10-15mins apart & getting ouchy
I'm hoping for drug free. Last birth I tried gas but it just made me less focused - and I felt like I needed to focus! I've had opiates for pain relief with a broken bone before and I reacted badly - so that's out. So epi is only real option if I feel I need it, & I think I'll only need it if the labour is particularly long & I get too tired to manage the contractions. So fingers crossed it's less than 25hrs, like last time!
