Amniotic fluid > HELP!

L

Hello ladies, I’m 30 weeks pregnant and today around 10am I was having really bad pelvic pain , back and leg pain ... when I went to pee I noticed my underwear was a bit wet And I didn’t pay no mind .... later that day around 3pm I went to the pee and I noticed a hugeeee difference in my underwear it was extremely wet but it didn’t passed thru my pants but it was so wet I was in shock.... I’m just not sure if is amniotic fluids or just an increase in vaginal discharge..... it was clear and it looked like water it had no smell and it had a tiny bit of white... has anyone experience this before???
