Pain left side

Bella

So last night a pain started in my left side groin area and it feels like a rubber band stretching. I've had the pain before now and it went away but this time its lasted all day and I cant lift anything without it causing more pain. Just wonding if anyone else has experienced this and if I need to be worried or not about going to get it checked out I'm almost 27weeks along now and I have a marginal card insertion so that's why I'm a little more worried.
