Platelet levels keep dropping

So I’ve been having my numbers checked pretty regularly bc they were dropping a little and I’m now 37+2 and my platelet levels went from 142 last month down to 118. Just wondering if anyone experienced anything similar? I’m so nervous they will drop below 100 and I won’t be able to get an epidural. I had epidural with my last two babies and can’t imagine not having it this time around 😩😩

Just looking for some feedback or experiences from anyone who might have gone through this?
