Round ligament pain??

Hey ladies- I’m 12 weeks and 2 days today and having pain below where my uterus is located. It feels like when you stretch a muscle too far type of pain. No blood, cramps, or anything else to follow the pain. When I’m sitting down it’s fine but god forbid I get up and walk, it doesn’t feel too great then!! I’m wonder if it’s because I spent an hour driving in normal (non maternity) jeans or if it’s Round Ligament pain? I normally would call my doctor but she’s in delivery Friday afternoons and I don’t feel like this is an emergency phone call situation.
