Help. SOS

I’m a first time mom, 32 weeks pregnant & I’ve been laying down in my bed like I always do, just recently twice within the hour I’ve been peeing or it feels like I’m peeing uncontrollably. Before it happens, it just feels like discharge leaking, so I’ll go & grab a tissue to wipe it up but then BAM constant idk if it’s pee or what but liquid tryna come out without my control. So I run to the bathroom before I make a mess on my bed and stuff 🙏🏼 thankfully my bathroom is not that far. I’ve had to change my underwear twice because of this. What should I do? Is this normal? Should I be concerned?
