Almost there

30 almost 31 weeks baby still breeched!!! It worries me some bc with my some everything was so perfect besides how I ate and with this one it's totally different and I have read where some babies are born in that breech position and I'm hoping he will continue to be healthy... His heart rate is always and only around 145-146 at max and I don't even know if that's normal ugh I just need some advice is anyone else in my boat or has been in the past????
