Possible pregnancy signs?

Haley

Okay guys so I am just wondering if anyone has experienced this before and I've looked it up and honestly I'm quite lost. So long story short had sex unprotected and I he came inside of me but I've been a little worried because I've been like having discharge. We had sex on Friday and it was my highest obviation day(it wasn't planned that way). It's kinda more so like thickish and a lot not just a little amount and it's been almost three days, do I expect this to go away? Is it a sign of pregnancy? Just wondering if any mommies experienced this and this is my only safe place to ask. TIA!
