37 weeks and lower pelvic aches/heaviness

Melissa • Due to have my little girl May 10th and I can`t wait!! 😍💕
Hi guys, so I'm 37 weeks now (yay) and I was just wondering if anyone else has experienced mild aches/heaviness near their lower pelvic area? 
I was told by my mum it's because baby is engaged now and that's where her head is lying but it does feel really heavy and was just wondering if anyone else has or is experiencing this?
