round ligament pain... maybe?

Molly
Okay I am 33 weeks pregnant and I was laying down for bed and had this awful sharp ripping pain in my lower abdomen like at my panty line the pain lasted for at least 30 seconds non stop. I haven't had any "round ligament pain" that felt like that but do y'all think that's what it was most likely? I'm sure this is a silly question! But thank you in advance!!
