Pee or amniotic fluid?

So I was eating watermelons an hour ago and suddenly the juice stuck in my throat and made me cough. While coughing I leaked a little bit. I don’t know if I peed or was discharge or amniotic fluid leakage.

I did go to pee right after but didn’t have the urge to pee. The leak didn’t smell anything.

I’m 24 weeks and at 20 weeks my doctor checked me for any leakage (looked down there and had me cough) it turned out fine.

What do you think it was?

I don’t recollect ever peeing while coughing or laughing. But I do get watery discharge sometimes.
