Baby In Pelvic Area??

Brittanie • Ariel Diana Nichole was born 9/7/16😊 Pregnant with my 2nd 💕
Not really sure how to explain this. I'm 29+4 weeks today. 2 days ago (so Monday) while I was laying down to go to bed, I felt Ariel drop down or stretch out realllllly low. I can't tell if she's just gonna be tall, or if she's upside down. I just don't know. I'm a FTM, and wouldn't know if this is okay, or if it sounded familiar to any of you ladies? No actual contractions, I have Braxton hicks every now and then but they don't have any type of time limit. Any advice would be great. Thanks girls! 
***She has stayed like that from that night on, and sometimes when she moves or kicks down there, it feels tighter, and stronger, and it sometimes hurts.
