Weird twinge like pain in vagina?? 23 Weeks pregnant

Bree • I`m 27 yrs old and have one son (8). I just had our second. Not sure if we're done or not.
Sorry. I keep getting werid twinge like pains in my vagina. Earlier it was a constant and now they are random? Is this just muscle spasms? Or something else? I see my doctor tomorrow. But if it's something I can tackle with say water for example I'd rather start tonight. Thanks!
