Scare today

Au
I'm 14w2d today and have been so happy about officially being in the 2nd trimester! 
I was out doing errands and started getting a dull achey semi painful cramping type feeling in my lower abdomen/uterus area. I haven't had any cramps since 6 weeks so it worried me. Called my dr she said come in. She did an ultrasound and baby is perfect, heartbeat is strong. So thankful!! She said she's sure it was round ligament pain! I had no idea it would feel like that. 
Anyone else felt round ligament pain yet?
