Sharp Abdomen Pain

I started feeling a sharp pain in my right abdomen a few days back and decided to have myself checked by my OB. She gave me Duvadilan and Utrogestan although if the pain persists after 1 week, I need to get a cervical funneling ultrasound. Pain Background: The pain went worse on the 3rd day and gave me difficulties walking. After 2 days, the pain is still present but would sometimes still give me a hard time to walk. I'm really worried because my OB said pain isn't normal at 19 weeks. Sharing this to get your thoughts as well. Thanks!
