"Lightning crotch" vs contraction??

As a FTM to be I've done research but I still feel kinda clueless and love the feedback I typically get on this app!

So it started last night and I had immense pain in my crotch/vagina area. I thought huh am I having a contraction right now? It took me by surprise and kinda took my breath away a bit, it was hard to move.. I looked into it and it sounds like more of "lightning crotch" but the last couple of days I've been having quite a bit of pressure in my pelvic area. I know from the baby's head being right there.

So I guess my question is how do you know if it's lighting crotch or a contraction? Contractions are typically more consistent? Could it be signs of soft labor?

I feel like I've also had more clear discharge, which from reading I hear can be normal?

Sorry for all the questions, just would like to know what's going on with my body!! Lol
